I have a dilemma. My father is getting re-married in June and I'm so happy for him to have found someone again. The problem is about 6 months after we reserved our cabin and everything for his wedding, my brother-in-law got engaged and his fiancé chose the same weekend as my dad. We let my husband's brother know immediately (before they even made save the dates) that we already had plans to be in Kentucky that weekend so he tried to change the date with his fiancé. She threw a fit and cried so he gave up. She randomly chose the date not even realizing it's father's day. It was going to be inconvenient and expensive but my husband was going to fly to Florida very early the morning after my dad's wedding so he could make it to both. Saving grace and making it clear that we had committed to the first wedding at least 6 months before they got engaged. Well...now I find out the future sister in law is now saying unless my husband misses my dad's wedding, that we had already reserve a cabin for and everything, then he is kicked out of the wedding party, but also their other brother will be kicked out of the wedding as well. I don't see how this is fair to anyone? My brother in law is perfectly ok with my husband getting there the morning of the wedding but he doesn't get a say in the matter, she throws a tantrum and cries. We live in California by the way so it's a lot of traveling in the first place. I was my sisters maid of honor back when she got married but there were circumstances that made me miss the rehearsal, and everything still went just fine. I don't understand this at all. He isn't even a best man or anything and she's having them rent khakis since its a more casual backyard affair. Why is she giving this ultimatum? Can someone help me understand or offer some advice?
