Girl made out with some random guy last night at the bar. I figured she did since she was suppose to call me for a ride afterwards and didn't. Long story short, she had a history of cheating, usually for attention because her ex neglected her. She made out with this guy while she was piss drunk and didn't remember anything until her friend told her. We hung out earlier today before she talked to her friends and she just came over and told me what happened after taking to her friend. I've told her before that she loses control when she gets drunk. I don't know what to do. Kinda hurt, but I already knew that it happened (intuition from prior cheating), so I didn't get mad at all. She knows about me being cheated on before.
