My FI and I have been having differing opinions on a key issue of his Bachelor Party. We were recently visiting his Best Man, and he asked who my FI would like invited to the bachelor party. My FI said that just the groomsmen is all he wanted, which seemed pretty standard to me, no big problems. That is until he felt the need to add that it did not include my brother, who is a groomsman. I feel like that is horribly rude to single him out like that. If something like that happened to me it would hurt my feelings, but my FI doesn't see it that way. Oh, and also, my FI asked my brother to be a groomsman on his own, I had nothing to do with it, so I can't see why he wouldn't want him at the Bachelor Party. Should I try to resolve this issue, or just let it go? It really bothers me to know that my Brother's feelings could be potentially hurt, and I didn't do something to stop it, but I don't know what to do.
