My MIL has very generously rented a house for a couple weeks this summer and invited all of her kids and their families (there's 5 siblings+4 spouses and three couples have kids, so it's a lot). They didn't have any money growing up and a few years ago she was finally able to get a much better paying job and she is very excited about being able to do this, it's a dream of hers. I will be seven months pregnant when we go on this trip.
Two of my husband's siblings and their spouses are just very toxic people and we are low contact with them. His other siblings we are close with. They always talk about couple X and Y and whatever marriage/family problems they have or whatever fights and drama they are picking with everybody else. I am very glad to just avoid them and they were not invited to our wedding, so they don't particularly love us either. But the few times a year we do end up seeing them my husband and I just don't engage when we think they're trying to start something.
There are three rooms with attached bath in the house, a basement with a couple of twin beds and a pullout couch, and various other pullout couches/sleeping options in the house. My MIL really wants to come on this trip and offered us one of the bedrooms with the attached bathroom because of how far along I will be. This was incredibly kind of her and she is giving up having her own room and rooming with my SIL (only single sibling) to do so. This is incredible generous of her and my husband and I have said several times we think that she should have the private room since she's paying but she is very insistent she wants us to have it.
Enter Couple X and Y, who both have children, and are very upset that husband and I are being given one of the private rooms despite us not having any kids yet. They are making this an entire thing. My husband has been dealing with it without me but I can feel us getting pulled into their vortex of toxicity even though he is trying to keep it brief and I know this won't be solved when the trip comes around. Even though MIL is very insistent that she is paying and it is our room, they of course can't leave it alone.
This is the first "drama" we've had directly with them in a few years. When we got married and they asked my husband why they weren't invited he sent a short and simple text explaining politely why and directed all further questions to MIL. But we were able to avoid them afterward whereas we are going to be in a house with them here.
My solution is that husband and I should just get our own place and be done with it. The only thing is that I know it's very disappointing to my MIL. One of the first times I met her she told me about wanting to do this and imagining it when they were all kids. She never thought it would happen. But I also think she's trying to force a situation that just won't work. She's done a lot of work to get this together and I really appreciate it. But I can barely handle them on a good day and I can't imagine trying to handle them when I'm seven months pregnant. My husband says we can do that if I want but he really wants to make it work for his Mom. He thinks he can handle them as we do normally. But I haven't really been the target of their ire before. Part of me wants to make it work for him and part of me wants to get the place and be done with it.
AITAH?
