Well Im posting this because I'm at a bit of a crossroads and I really dont want to make the wrong decision, so I come here for advice. I've known my girlfriend for 2 months now and have been going out for the past month(1 month tomorow). I almost never get to see her due to the fact that she is constantly grounded for her crappy grades in school. Last night I went to my friend's(ex girlfriend from2 years ago) house and drank some vodka with her and ended up fucking her. In regards to that kinda stuff I havnt done that much with my girlfriend. Now I feel like im starting to loose my feelings for my girlfriend and Im also looking forward to the next time I can have sex with that friend. I dont know If I should a) tell my girlfriend and break up with her, b) dont tell her c) break up with her and dont tell her?
