After Uncovering His Affair with Her Sister

I couldn't sleep after discovering Logan's betrayal. The image of his watch—our forever gift—listed for sale haunted me. By morning, I had made a decision. If Logan thought he could humiliate me and walk away unscathed, he was about to learn how wrong he was.

I called Marcus Chen, my business partner and one of the few people I trusted completely.

"I need a favor," I said without preamble when he answered. "A private investigator. The best you know."

Marcus didn't waste time with questions. "Done. I'll have someone at your place by noon."

The investigator arrived promptly—a woman named Diane with sharp eyes and a no-nonsense demeanor. I explained the situation clinically, as if I were discussing a business deal gone bad rather than my personal life imploding.

"I need to know who he's been seeing," I concluded. "And I need proof."

Diane nodded, her expression revealing nothing. "Social media analysis, phone records, surveillance if necessary. We'll find out."

I handed her Logan's basic information—his university, his major, his social media handles. "He thinks I'm oblivious," I said, my voice hardening. "Show him how wrong he is."

The waiting was excruciating. I threw myself into work, reviewing contracts and proposals with unusual ferocity. My assistant gave me concerned looks when I snapped at her for a minor typo.

Three days later, Diane called requesting an urgent meeting. My heart pounded as I cleared my schedule and waited for her arrival.

"I have the information you requested," she said when she arrived, placing a manila folder on my desk. "You might want to sit down."

I remained standing, arms crossed. "Just tell me."

"The woman Logan Warren has been seeing is Lilyana Bennett."

The name hit me like a physical blow. Lilyana. My half-sister. The girl who had grown up in the home that should have been mine, surrounded by the father who had kicked me out at sixteen.

"That's impossible," I whispered, but even as I said it, I knew it was true. The pieces were falling into place—Lilyana's sudden interest in my life over the past few months, her questions about Logan, her overly sweet concern about our relationship.

Diane opened the folder and spread out photographs on my desk. Logan and Lilyana entering a hotel. Them having dinner at an intimate restaurant. Her head on his shoulder at a football game.

"They've been seeing each other for at least four months," Diane said quietly. "Based on phone records and social media activity, they're in regular contact even when you and Mr. Warren are together."

I stared at a particular photo—Lilyana wearing the necklace I'd given Logan for Valentine's Day. The one he'd claimed was "being resized."

"There's more," Diane continued. "Ms. Bennett has been selling items you've given Mr. Warren. Here's the evidence."

She showed me screenshots of Lilyana's online marketplace account where she was selling the designer clothes and jewelry I'd given Logan over the years.

The betrayal cut deeper than I thought possible. Not just Logan, but my own sister—the one person who should have understood what it meant to be abandoned by family.

"Thank you," I managed to say, my voice surprisingly steady. "Send me everything digitally and bill me for your services."

After Diane left, I sat alone in my office, staring at the evidence of their betrayal. The pain was there, but something colder was taking root beneath it—a determination that would not be denied.

I was still sitting there when a wave of nausea hit me suddenly. I barely made it to the bathroom before emptying the contents of my stomach.

Morning sickness, I realized with a shock. I'd been attributing the nausea to stress and betrayal, but now...

I fumbled through my desk drawer for a pregnancy test. The first one showed a faint line. The second, stronger. The third, unmistakable.

Pregnant. With Logan's child.

I sank to the floor, the test still clutched in my hand. The timing couldn't be worse. Or perhaps, from another perspective, it couldn't be better.

As I sat there, one hand instinctively moving to my stomach, my phone buzzed with a text from Logan.

"Miss you babe. Can't wait to see you next month."

The lie burned brighter than ever now. Knowing what I knew about him and Lilyana, there was no way I could bring this child into the world. No way I would give them both the satisfaction of my complete destruction.

I looked down at the positive test again, then back at the photos of Logan and Lilyana together.

"This changes everything," I whispered to myself, a plan already forming in my mind. "Everything."
