Please help. :(
I'm getting married in a week, and a few days ago I got a call from a man I know saying that he has been sleeping with my girlfriend for a year. I won't bore you with the details (that's all in my own Live Journal) but I've been with my girlfriend for 5 years, and I love her very much, but I have no idea how to handle this becuase I think he's telling the truth.
I know I have to talk to her, but I don't know how to. I just have no idea were to begin, and I only have a week to decide what to do.
Right now, any advice at all would be very much appriciated.
Thank you.
