So I have recently booked the restaurant for my rehearsal dinner. My fiance's parents are paying for it and becuase they have recently been let go from their jobs, we have opted to go low key and very small. We are only inviting people in wedding (with their spouses), readers, grandparents, and my brothers. I have repeatedly made it clear to my family that we are keeping it small and explained why. Here is my problem--for some reason, my brother decided to invite his girlfriend to the rehearsal dinner without me being aware of it. I found out over the holidays when they mentioned how much they were looking forward to eating there. My question is--how do I univite her--she was never on my list and only a ring on her finger would have gotten her there--she has been very disrespectful to my mother and I really don't want her at the dinner--thoughts? suggestions?
