Ok - I have a messed up senario going on with some guests. Long story, short...The best man (Mark) was dating/living with his girlfriend(Sarah). Then they broke up and a friend of all of ours(Joe) began dating her. So Joe has been invited to the wedding and plans on coming with a guest, which I'm assuming would be the ex of the best man. I'm not sure if the best man has an issue with his friend dating his ex, but I really don't want her to come. First of all, I don't want to risk there being drama between them. Second, I have never liked Sarah and don't feel like catering to someone who has never been respectful to me or my fiance. Am I being out of line?? How should I deal with this? I'm not a bridezilla AT ALL, and don't want to come off rude, but I basically want to tell Joe that he cannot bring her. HELP!!
