The Mistress Wanted My Research Career

When I slid the divorce papers across the kitchen island toward Simon, my voice sounded like it belonged to someone elsesomeone carved entirely out of ice.

You walk away with nothing, I said. That is your only option.

Three days ago, I was pulling an all-nighter in the lab, furiously formatting my dissertation, when my phone screen lit up. It was an Instagram post from the newest PhD student in our research group, Paige. She had uploaded a screenshot of an acceptance email from Nature Chemistry, listing her as the first author. In the second photo, she was smiling brightly in the lab, Simons hand resting intimately on her shoulder.

Everyone in the department knew that the novel catalyst project was mine. I had bled for it since my first year of grad school. It was my lifeline. To get those stability metrics, I had spent over three hundred sleepless nights in the cleanroom. I had even hidden my wedding ring on a gold chain under my scrubs, wearing latex gloves to conceal the phantom indent on my finger.

But when I confronted Simon, he just brushed it off. "Paige helped you polish the abstract," he said, not even looking up from his laptop. "That counts as a co-contribution."

Later that afternoon, standing by the fire doors in the stairwell, I heard Paiges voice echoing from the floor below. She was whining, laying on the baby voice thick. "You're so biased, Dr. Adler. I just told you I was stressed about my prelims, and you practically handed me Carlin's paper."

Simons low chuckle floated up the stairs. It sounded like a velvet-wrapped ice pick. "Shes fully funded on that NSF grant," he murmured. "Losing one first-author credit isn't going to kill her."

Three years of a secret marriage, outweighed by a few manufactured tears. The research I had poured my soul into was nothing more than a poker chip to him, traded away to buy a younger woman's affection.

Before I even had the chance to move the tassel on my graduation cap, my marriage and my academic future had shattered into a million jagged pieces.

Now, looking at him across the granite countertop, I only wanted one thing. I wanted this man, along with his twisted sense of "fairness," completely eradicated from my life.

...

The day Paige joined our lab, Simon personally gave her the grand tour. He finally stopped at my bench.

"This is Carlin, a senior PhD candidate and the unofficial manager of the lab," Simon said. His tone was perfectly sterile. Professional. "If you need anything, ask her."

I pulled down my safety goggles and offered her a warm smile.

Paige didn't look like a typical stressed-out grad student. She was wearing a tweed designer jacket, her nails were perfectly manicured, and there were faint, sophisticated laugh lines at the corners of her eyes.

"Hi, Carlin. Its so nice to meet you. I'll be counting on your guidance."

When she spoke, Simons gaze lingered on her. There was a softness in his eyes, a microscopic shift in his posture that made my stomach drop.

I told myself I was being paranoid.

But that night, for the first time in our marriage, Simon claimed he had to "finish a grant proposal" and slept in the guest room.

The unease settled in my chest, a quiet, persistent hum.

The next day, I was under the tissue culture hood, splitting cells. My lab mate, Ben, rolled his stool over, lowering his voice to a conspiratorial whisper. "Hey. Do you know the actual story with the new girl?"

I was still distracted by the phantom chill of the empty bed beside me. "What story?"

"She did her undergrad in this lab a few years ago. Went out into the corporate world, and now shes suddenly back for her PhD." Ben leaned in closer. "I heard... I heard shes the reason Dr. Adler got divorced the first time. Apparently, his ex-wife found their texts. Total scandal."

My hand twitched. The tip of my micropipette plunged straight into the biohazard waste beaker.

"Don't spread rumors like that," I said. My throat felt like sandpaper.

"I'm just telling you what the postdocs say," Ben muttered, shrinking back a little. "Just watch your back, Carlin. He treats her differently."

I murmured an acknowledgment and returned to my cells, but it felt like someone had poured liquid nitrogen down my spine.

Texts? An affair?

When Simon and I married three years ago, he told me his first marriage fell apart because his wife wanted to move to Europe and they simply grew apart.

Had he been lying to me this whole time?

But Simon had always been so good to me. When I was a senior undergrad, he was the brilliant young assistant professor who patiently taught me how to design experiments and write fellowship applications. I grew up with no money, so he created a paid lab manager position just for me, adding an extra twelve hundred dollars a month to my meager stipend.

The year we got married, he had just been granted tenure. I was starting my PhD. To avoid Title IX complications and department gossip, he insisted we keep our marriage a secret. The lab manager stipend quietly transitioned into him transferring two thousand dollars a month into my checking account. A husband allowance, he had joked, kissing the top of my head.

I refused to believe he could betray me. It was just academic gossip. I forced myself to forget it and bury myself in my work.

But things started happening.

During Paiges first month, my personal micropipette went missing. It was the one Id used for three years, marked with a tiny dot of crimson nail polish. I tore the lab apart looking for it.

I finally found it sitting squarely on Paiges bench.

"Oh, this?" She looked up, her eyes wide and innocent. "I found it lying around and assumed it was a spare. You don't mind, do you?"

I took the pipette back without a word.

In her second month, my cell cultures got contaminated.

I came in at 6:00 AM to get a head start. The lab was silent, except for the low hum of the incubators. Paige was standing right in front of my incubator shelf, holding one of my culture flasks.

"What are you doing?" I asked, my voice sharp in the quiet room.

She turned around. Her expression didn't even flicker. "Just checking out the morphology of your cells. Learning the ropes. Is that a problem?"

I stepped past her and pulled out my trays. Two months of grueling, early-morning work. Every single flask was cloudy, floating with white fungal fuzz. Dead.

Paige stood beside me and let out a soft, theatrical sigh. "Oh, no. What a shame. Try not to let it get to you, Carlin. This kind of stuff happens all the time in bio labs. You can just redo it."

She said you can just redo it with the breezy cadence of someone commenting on the weather.

I stared at her for a long time, searching her face for a crack, a sliver of guilt. There was nothing. She smiled back at me, utterly bulletproof.

That night in our apartment, I couldn't hold back the tears as I told Simon what happened.

He was eating takeout at the dining table. He paused, setting his fork down, and looked at me with mild disapproval.

"Carlin, you're the senior student here. You need to be a little more forgiving. Shes just trying to learn. I highly doubt she did it on purpose."

I stared at him, stunned. "Forgiving? She contaminated two entire months of work! You know how hard I worked on those lines!"

Simon frowned. "Do you have proof she contaminated them?"

"The lab camera is broken."

"Then you don't have proof. And without proof, it's just a baseless accusation."

I swallowed the hard lump in my throat. "Simon. You don't believe me?"

He sighed, pinching the bridge of his nose. "It's not about not believing you. It's about maintaining a professional environment. Paige was my student years ago. I know her character. She wouldn't do something malicious."

I put my hands flat on the table. "Simon. I am your wife."

He fell silent for a few seconds. When he looked at me, his eyes held the weary patience of a man dealing with a petulant child.

"Exactly. Because we're married, I need you to be the bigger person here. Don't turn the lab into a toxic environment over a minor setback."

A minor setback.

My cells dying was a minor setback. I wondered, then, what constituted a major one.

In Paige's third month, Simon took a sub-project that was entirely mine and handed half of it to her.

He called me into his corner office. His tone was gentle, almost pleading. "Carlin, youve got so much on your plate right now. Paige is struggling to find her footing. If you let her take the lead on the secondary assays, itll take some pressure off you. Ill make it up to you tonight, I promise."

It felt wrong, like a stone settling in my gut, but I didn't fight him. I nodded. I convinced myself it was just a PI managing his lab, just a husband looking out for his stressed wife.

Six months later, during our weekly lab meeting, Paige stood up to present her progress.

Every single data point on her slides was mine.

I sat there, frozen in my plastic chair. Those were my preliminary trials. I had spent an entire semester optimizing those concentration gradients, coming in at midnight to take time-points. I hadn't even drafted the manuscript yet, and here they were, perfectly formatted in her PowerPoint.

"These metrics..." I started, leaning forward urgently.

"These metrics build beautifully on the preliminary data Carlin gathered," Simon interrupted smoothly, his voice projecting across the conference room. He didn't even look at me. "Paige took that foundation and really ran with it. Excellent work, Paige. I think we're looking at a solid publication here."

The room went dead silent. I could feel Ben and the other postdocs staring at me with deep, uncomfortable pity.

The light in my eyes just... died.

At the front of the room, Paige looked down at the podium. But I saw the corner of her mouth curve up. It's mine now, that smile said.

When we got home that night, I cornered him in the living room.

"Simon, that data was mine. Its unpublished. How could she just present it as her own?" I kept my voice low, terrified the neighbors would hear the tremor in it.

He leaned back against the sofa cushions, looking exhausted and annoyed.

"Carlin, part of being a senior PhD is mentoring the juniors. Besides, data generated in the lab belongs to the lab. What does it matter who writes it up? You have three other projects. You don't need this one."

"But"

"Enough. Stop being so territorial."

He stood up and reached out to pull me into a hug. I flinched, stepping out of his reach. His arms dropped.

"Look," he said, his voice hardening slightly. "When you graduate, you're going to leave all your protocols behind for the younger students anyway. We're a family, Carlin. My success is your success. If Paige publishes a high-impact paper, it makes my tenure package look incredible. Aren't you happy for me?"

A family.

I stood in the dim light of our living room, looking at the man I had slept next to for over a thousand nights. He looked like a stranger.

That was the moment I finally understood. Only Paiges problems were major problems.

As I was wrapping up my dissertation, Simon called me into his office.

"How is the novel catalyst paper looking?" he asked.

My heart did a nervous little stutter. "Good. I'm formatting it for submission next week."

He nodded. Tapped his pen against his desk. The silence stretched until the air felt thin.

"Listen," he finally said. "Paige mentioned she did quite a bit of troubleshooting on that protocol. Go ahead and add her as second author."

I felt a bizarre, out-of-body sense of inevitability. Of course.

I swallowed the bile rising in my throat. "What exactly did she do? Name one thing she contributed to this project."

"She maintained your cell lines when you were writing, didn't she? She helped you clean up the datasets?"

"Maintained my cells? You mean the ones she deliberately contaminated"

"Stop it," he snapped, his patience evaporating. "Adding her as second author costs you absolutely nothing. Shes new, she needs to build her CV, and its your job to help her."

I stared right into his eyes. He broke eye contact first, looking away toward the window.

That evening, I stood at the stove, frying vegetables. The oil sizzled loudly in the pan, mirroring the chaotic static in my brain. Simon was in his home office, supposedly reviewing manuscripts.

Something was fundamentally wrong. I couldn't articulate the exact shape of it, but the shadow it cast over my life was suffocating.

Over dinner, I set my fork down. "Simon. Do you have feelings for Paige?"

His chopsticks paused in mid-air. A microscopic tightening of his jaw. "What is that supposed to mean?"

"It means... you treat her differently. You protect her."

He set his bowl down and let out a long, theatrical sigh. "Are you seriously jealous right now, Carlin?"

I let out a harsh, incredulous laugh. "Shouldn't I be? I'm your wife. She is your student. Do I really need to list out exactly how blatantly you favor her?"

"She was my student years ago! Im just looking out for her!" His voice rose, bouncing off the kitchen tiles. "I did the exact same thing for you when you joined the lab! What exactly are you accusing me of?"

But he was omitting the most crucial detail. When he was "looking out for me," we were already sleeping together.

I looked down at my plate, hiding the bitter sneer forming on my lips. "I'm not accusing you of anything."

"Then drop it." He picked up his bowl, his face a mask of cold fury, and went back to his meal.

Watching his profile, I suddenly felt incredibly foolish.

When we got married, he told me academia was deeply biased against young female scientists. If people know were married, theyll say you slept your way to your PhD. Theyll diminish your brilliance. Keeping this quiet protects you.

I swallowed it whole. Because of that, no one in the department knew that after the lab lights went out, we drove to the same apartment and slept in the same bed.

He told me academic politics were treacherous. We had to be flawless.

So, I never walked into the building with him. We never ate lunch together in the courtyard. I never claimed him in public. Even my wedding ring was relegated to a secret chain around my neck, hidden beneath the collar of my shirts.

Back then, I thought none of it mattered, as long as we loved each other.

It was all a lie. It was just a convenient way for him to hide me. Because clearly, he had no problem openly favoring a student when he actually wanted to.

I was nothing but a living, breathing joke.

In the spring of my final year, I finished the manuscript for the novel catalyst project. Before I submitted it, Simon called me into his office and said he had made some final edits. He wanted me to review them.

I opened the Word document on his monitor. My eyes locked onto the very first line.

Authors: Paige Sutton, Carlin Adler, Simon Adler.

Paige was first author. I was second.

The blood drained from my face. I looked up at him.

"Simon," I whispered, the tremor in my voice impossible to hide. "This is my project. I did all of it."

"I know." His voice was utterly calm, adopting the detached cadence of an administrator making a budgetary cut. "But Paige did a lot of the backend data visualization. And frankly, Carlin, her writing is just stronger than yours. The narrative flows much better after her edits. Giving her first authorship doesn't hurt youyou're still a co-first author on paper. It's enough."

"Enough?" My hands were shaking so hard I had to grip the edge of his desk. "This is three years of my life. This was the cornerstone of my dissertation. How am I supposed to secure a postdoc without a sole first-author publication on my main project?"

Simons face darkened. "Are you questioning my authority as your PI?"

I didn't answer.

He sighed, adopting that patronizing, sickeningly gentle tone again. It was the voice of a god handing out scraps.

"Look. Ill assign you a new, fast-track project. I guarantee youll be first author on the next one. Just let Paige have this. She needs this publication to qualify for the departmental fellowship. You already have your funding. You're a fifth-year, one paper won't break you. Let's talk about it at home."

I stared at him, desperately searching his face for the man I used to know. The man who held me when my mother died. The man who promised to protect me.

There was nothing there. Just cold, calculated self-interest.

"What about my fellowship applications?" I asked softly.

"You already won the NSF grant your second year. Give the younger students a chance. Shes older than you, she's feeling the pressure."

I dug my fingernails into my palms until they ached.

Older. Feeling the pressure.

What about me? I am your wife. What does my pressure, my anxiety, my future mean to you?

"We will talk about this at home," I said, and walked out.

He didn't come home until late that night.

I sat on the living room sofa in the dark, waiting. At 11:00 PM, the lock clicked.

When he walked in and saw me sitting there in the shadows, he flinched. "You're still awake?"

"I was waiting for you."

He took off his shoes, walked into the living room, and sat down on the armchair across from me. He looked deeply uncomfortable.

"Go ahead," he said.

I looked at him, my voice completely flat. "Why did you really give my paper to Paige?"

He let out a heavy breath, running a hand through his hair. "Carlin, I already explained this to you. She needs"

"I don't want the HR answer. I want the truth."

He went silent. The silence stretched so long I could hear the faint hum of the refrigerator in the kitchen. I thought he was going to refuse.

Then he spoke. His voice was hoarse, fractured.

"Because she's pregnant with my child."

A gust of wind rattled the apartment windows. The apartment was suddenly freezing.

I stared at his face. The face I had loved for five years. He looked entirely alien to me.

"What did you just say?"

He dropped his gaze to the floor. "Paige... she's pregnant. It's mine."

I stood up. I sat back down. My brain was a wall of white noise. I didn't know what to do with my hands.

When I finally found my voice, it was barely a whisper. "When?"

"Three months ago."

"Three months?" My voice cracked, rising in pitch. "We have only been married for three years!"

He looked up at me, his eyes swimming with something that looked like guilt. "Carlin. I am so sorry."

I'm sorry.

I'm sorry.

I'm sorry.

I didn't want his apologies.

I stood in the center of the room, my whole body vibrating. "Simon, you made me hide our marriage. You said it was for my career. You told me to let her abuse me in the lab, because she was just a junior student. You forced me to give her my paper, because she needed it. And now you're telling me she's pregnant with your baby?!"

He didn't speak.

"Look at me!" I screamed.

He looked at me. And in his eyes, beneath the guilt, I saw something else. Something that broke me completely.

Relief. He was relieved it was finally out.

"Carlin, I'll handle it," he said softly. "Just give me some time."

I unclenched my fists. I took a slow step back. Hot tears spilled over my eyelashes, hitting the hardwood floor.

"Time?" A bitter, jagged laugh ripped out of my throat. "I gave you three years, Simon. What did you give me?"

I looked at him with absolute clarity.

"I don't want your time. I want a divorce."
