We have received gifts from people that FMIL invited to our engagement party behind our backs. We ended up changing and hosting our own engagement party ourselves because she wouldn't UN-invite them. They are people we don't know. They are also not invited to the wedding. What do we do about the gifts they've sent us? I feel that it is FMIL problem to solve, but these people are just caught in the middle. Even though I don't know them I don't want to hurt their feelings.
