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
