I’m getting marry early in 2020. My invitations were very formal with an inner envelope specifically stating who was invited. My fiancé has one brother who is married and they have a 2 and 1 year old. I specifically wrote just the parents’ names on the inner envelope as I don’t think that they will enjoy the ceremony and evening reception if they are tending to babies. We love the babies and help babysit them from time to time.
They never sent in a RSVP, so I recently reached out via text confirming she would be able to be there. I knew my fiancé’s brother would be there as he is in the wedding. She responded that “we *all will be there!” How do I respond without hurting feelings or seeming like a controlling bride?
