Basically my GF of nearly a year admitted on a recent solo holiday she had sex with the guy that installed the gas where she was staying.
I thought I could handle this because I strayed in the early days of our relationship. Turns out I cant. I want to know all of the intimate details of this fling and feel as though she really betrayed me. Its like she is telling me it was just sex and the were both partially clothed at the time, obviously sans underwear but I just dont believe her.
I think I need to dump her, but how??
