My bff is wanting to cheat on her fiance and wants to tell him she is spending the night at my house. I told her that is not a good idea. They have been having troubles for awhile now and she always turns to me for advice. I have told her before that she needs to end the relationship if she is that unhappy. She gets mad but she asks me. This time she won't talk to me. I know from experience cheating isn't the answer. You feel nothing but guilt. Am I wrong for not just supporting her?
