Basically found out that my "I swear im not a slut!" girlfriend fucked a whole frat house after a night where she was 'only going to hang out with someone and it just happened' except that someone was the very first guy she fucked so him and like 3 other of his frat brothers in one night, just 2ish weeks before meeting me. She swears it was a mistake and shes sorry and only wants me but I cant even look at her without seeing her getting railed facedown ass up by all of alpha beta kappa. do i run? i really do like her and want to be with her but fuck
