One of my good female friends seems to have a tendency to be rude to my fiance. She works at a place where my fiance has to frequent because of his job. Because of this, I am not usually around when they encounter each other. Of the last 5 encounters between the two of them, my fiance has come away three times feeling that my friend had behaved very rudely- being a B----. I had seen this occur once, and I spoke with her about it, but it apparently is continuing to happen. Yes, I do believe my fiance. After the last occurance, my fiance gave me the ultimatum- invite her to the wedding, he won't be there. How do I uninvite her? I have no idea where to start.
