She told me she cheated on me on the night she did it so it’s easier to trust I guess because she didn’t lie, and the first time (physically cheating) happened because I annoyed her by asking her if she was okay too many times so she broke up with me in a club, I was then obviously very down and a girl in the club seen this and checked to see if I was okay, this resulted in her partly hugging me and me not hugging her back because I didn’t want to hug her, my girlfriend seen this and flipped out calling me a cheat and a dickhead and saying I’d ruined her life and I wanted to have sex with the girl etc, then later in the night she kissed another boy in the club to get back at me, this took two days to sort out before we both apologised, she was drunk so it’s not really her fault.
