I don't know what to do. It's the worst thing in the entire world. One night when we were both really drunk and she was away, I had sex with my best friends boyfriend. This is COMPLETELY unlike me, whenever I'm in a relationship I'm devoted and faithful. Cheating makes me sick. There have been issues of cheating with people close to me and I hate it. I like him, we are close friends, and I've had an on and off crush on him, but I always thought that if the opportunity arose, id have enough self respect, as well as respect for my friend, to say no. they have been dating for over a year and he even told me that he's cheated on her before. Its bad stuff, but he really is a good guy. He loves her, but I don't think he is in love with her anymore, and he doesn't know how to let her down. I also have issues where I need guys attention, its bad and stupid and wrong but I don't know its how I am. But I can't believe we both took our issues and did something that will eventually hurt her so much. Some of our friends know and everyone I know keeps telling me that I have to make sure she doesn't find out, but I don't know what to do. I could never face telling her, but I'm not this person. I'm not this sick coward. She deserves to know. I can't do this. I don't know know who to talk to or what to do. But I guess it doesn't matter at all because I don't deserve it anyway. I'm the one who is wrong here. And nothing I can ever do will take it back.
