My BIL and his fiancé announced over the Thanksgiving holidays that they would be getting married the second Friday in December after some discussion with my ILs. They chose the day because all of the immediate family will be in town. Originally, they were talking about getting married in 2017, but found out recently that they needed to change it because of some paperwork.
My DH and I had made plans a few weeks before to celebrate our 10 year dating anniversary on that day, because my parents are coming from out of town the next day to celebrate Christmas early with us since we can't go there this year. We celebrate both our dating and wedding anniversary, but do more for our dating ann. because we wanted to have our wedding that day and were talked out of it by our families.
My husband and his brother don't get along well at all, but he did come to our wedding. We have been told that we have to change our plans now, because their wedding is Friday morning, but we are expected to be at the reception Friday night. We did tell my ILs that we were going out that night on our own before the announcement was made about the wedding date.
Am I being unreasonable because I don't want to change my plans with DH or is this one of those suck it up and deal issues?
