Dear Sugar, I've been living with my cousin ever since I was four years of age. She's a kind of sister to me minus the fights. When I was thirteen and she was eighteen, she started dating a man that was attractive and at first, charming. One night when my cousin was out, her boyfriend came back to pick up his coat. I ignored him and then he came up to me and said "You're one hot little number. If you weren't thirteen, I would have picked you instead of your cousin." I left the room and locked myself in the bathroom upstairs and fell asleep. Three years later, my cousin married this boyfriend of hers and had twins with him. I was happy for her but I still remembered the remark he made about me three years earlier. I had a boyfriend at the time that I loved a lot. Six years later, I married my boyfriend and we had three children. It was like a fairytale to me. But then he asked for a divorce. I was devastated. So, it took a year for the divorce to finish and I lived with my cousin again: with my three children and her two children. One night as my cousin was at a business trip, I went to a party and her husband was there hitting on several girls. I started talking to him and we got drunk little by little. I ended up going to a hotel with him and then, I just shut off. The next morning I woke up in his bed undressed. I knew what had happened. He then woke up and we started making-out and he was saying things like "I should have never married." or "I love you. Stay with me." Later on, I got dressed, took my stuff and left. I had a guilty feeling all over me. I knew what I had done was wrong but, I was then disgusted about the fact that her husband would actually cheat one. Four months later, I caught him at my cousin's apartment with another woman in his bed. I later was going through his stuff and found a card with a number. I called and it was the phone number to a place were hookers sleep with men. I asked if my cousin's husband (I used his name)had ever come and she said he came often. That was it, I was sickened. I need to tell my cousin because she believes that he is faithful to her and respects her. But, I'm afraid she will hate me for sleeping with him. I was drunk and completely unaware of what I was doing though. What should I do?
