So my FI just called me and apparently someone in his family is bad-mouthing us saying that the only reason we invited her to the wedding is to get a gift. In all honesty, we invited her because his grandmother asked us to and thought it would be nice for her to be there if she could. She already sent us a check and his mom called and wants us to send the check back with a note saying that we aren't accepting gifts, which is a lie. I don't want her money since she thinks it an obligation to give it to us. What do I do? I don't want to be rude, but I don't want that check either....I have more respect for myself than that.
