I have been with my girlfriend for our very a year now, and around our two month anniversary I started to cheat on her. I cheated on for 2-3 months,(with her best friend) and I feel really bad about it. I asked my girlfriend if I cheated on her, would she take me back. I really love my girlfriend, and I want to tell her, but I don't want her to leave me. I have lost sleep, and cried a lot because I don't want to lose her.
