I'm 29. We met when I was 23. She told me she works in banking and travels a lot for work. I believed everything. We've been together for 6 years. I was planning to propose next month. Last week, I surprised her at her 'office' with lunch. The receptionist said no one by her name works there. I was confused. I called her - she said she stepped out, she'll call back. She didn't. I went to her apartment. A man opened the door with a baby in his arms. He asked who I was. I asked who HE was. He said 'I'm her husband. Who are you?' My world stopped. Everything came out. She's been married for 4 years. They have a 2-year-old son. All those 'work trips'? She was with me. All those nights she 'worked late'? She was with me. Her husband travels for work (he's in oil and gas, offshore). That's how she managed it. I confronted her. She cried and said she loves both of us. She said she got married because her family pressured her, but she never stopped loving me. She said she's been trying to figure out how to leave him but she can't because of their son and his family's influence. She begged me not to tell her husband. She said it would destroy their son's life. I feel like the other woman, except I'm a man and I didn't even know. My friends are telling me to expose her. My sister says I should walk away quietly. But I'm MAD. I wasted 6 years! I introduced her to my family. My mother was already planning our traditional wedding. We've been intimate countless times - was she sleeping with both of us at the same time? Was she comparing us? When she said she loved me, was it true or was I just a side piece? Her husband seems like a decent guy. He doesn't deserve this. But will telling him make me a snitch or will it set him free from a lie? I have screenshots of everything - our chats, pictures, videos, hotel receipts. I have proof she's been living a double life. Part of me wants to burn her entire world down. Part of me still loves her and wants to understand how someone does this. How do you live such a massive lie for years?
