I had an affair with my fiance's best friend, I am truely sorry for it and very remorseful. I don't know how to talk to him, I'm afraid of saying the wrong things. I know this site is for the BS's, but can anyone help a WS who made a mistake and wants to fix it and make it better. Seriously, I really could use some help, and any advice would be more than appreciated, the more the better,for us.
