I just found out tonight that my girlfriend cheated on me about two weeks ago. i found this out from a friend. my girlfriend told this to her on prom night, at my girlfriend's house as we camped out. that wsa 4 days ago. my friend just told me today, and i am mad i didnt know sooner, but glad that she told me. my girlfriend and i have been dating for 7 months today, but have had a strained relationship over a long period of time latley, and now with this added information i dont know what to do. i am resolved to talk with her. we set a date for friday earlier today, before i knew, and i think im going to bring it up then. ive thought over beating around the bush, and just out right saing i know. im not sure which the best path would be. any help on how to speak to her about it would be an immense comfort. this is the first time this has happened to me and i dont know how to handle it

lately, my girlfriend has been acting very weird. one minute she is very reseptive to my loving gestures, the next she is stand-offish and cold. i know she is stressed about leaving for college in june and all that, but lately i cant even get a hug out of her. she doesnt call, or even try to see me at all. i havent kissed her in at least a month. barely even get a good bye hug from her. we have been dating for about 7 months now, and its just recently she has begun to act liek this. i just need a little advice on how to make everything back to teh way it was when we first started dating. those were the days, but like i said now, i cant even get a hug half the time. at this point i am willing to try just about everything.
