The FH and I have the two people who were are friends with. They use to be married and had a very very ugly divorce. We use to brunch with this couple twice a month. The guy is a distant relative of mine. We are still in touch with both of them. she has since remarried and now has an adorable baby boy. I want to invite both of them to my wedding, but I would be so upset if the ex or his family treated her and her husband bad. I don't think I am going to invite his family, just him.
my question is, is there a proper way of going about this situation? should I talk to both of them about it?
