My sister-in-law is getting married this September. When my parents who live abroad said they wanted to come and visit us in September, my husband asked his sister if it would be ok to invite my parents to their wedding. We told them there was no pressure, it was just to figure out if we should tell my parents to avoid the weekend of their wedding, or to come at the same time of the wedding. The bride said it would be no problem for my parents to come, so they went ahead and booked their flight so that their stay would include the weekend of the wedding. A couple of months later, the bride started to get stressed out about the number of invitations she is having to send out, and has now told my husband she is having second thoughts about whether it's ok for my parents to come or not. She said she will decide last minute. My parents keep asking us what present they should buy, and what hotel they should book for the wedding (the wedding will not be in our town).
I am pretty upset about this situation, because we asked her in advance if it would be a problem - we asked before my parents booked their flight and before we made plans. My husband doesn't know what to say to his sister, but I also really don't know what to say to my parents. Who is in the right here? How should we proceed? I feel sort of insulted by this situation and I am considering not going to the wedding anymore. I see my parents only a few times per year, and don't want to miss out a weekend with them while they are here. If they are no longer invited to the wedding, I would prefer to spend the weekend with them and miss the wedding. But I know if I don't go to the wedding, my husband will be pretty upset. What should I do?
