my exgf told me some guy was hitting on her all night and tried to kiss her at her brothers party.
she said later her brothers friend told her brother they hooked up and she said it was bs or something.
it took me a while to figure out why the fuck she would tell me either of those because i woulda never found out, but then i realized that women are liars, and suck really bad sometimes at it, or are really good at it sometimes.
the reason i tell you this is because if a girl will tell you something like this, that means she did worse.
she most likely fucked him, and someone you both know or that you could possibly find out from saw them kiss eachother. she confessed about the kissing so you would trust her, and not believe whoever will tell you that they fucked.
ditch her or like nimbus said, fuck her friend to even the ground. no ifs and or buts no matter how hot she is she cheated
