I'm the bride and my mother and father have been divorced for 4 years. My mother didn't want the divorce and makes that very clear everytime the subject comes up. She still seems pretty hurt about it. My father found a very nice lady over a year ago. Both my fiancee and I find it appropriate for my father to invite his girlfriend, but we can also see where that could get uncomfortable. Most likely, she will come and that's fine. But how do we avoid conflict? Is there a seating arrangement that we could adhere to? Not a lot of my side of the family will be there besides those three, my brother, and possibly my my mother's brother and his wife.
