Step daughter visit


My husband’s daughter and grandson spend the holiday weekend with us at my invitation and I also invited the 12-year-old to stay for the week to help her out with childcare (they live five hours away) and to try to create a family dynamic. (I don’t have grandchildren yet but I have two kids in their 20s and hope for some someday!).
The trouble is that my husband barely talked to them and left me alone with her while he puttered around the house, washed the car, etc. It felt like I had to do all the work and he was just as remote as he is when my kids visit. I guess my hope was that by being nice to his family, he would be nice to mine.
I am having a cascade of negative thoughts about both of them and dreading the week. Also I am totally judging my husband for not being able to relate to his daughter and grandson and for being cranky with me. The point is that I want him to behave a certain way around his family to make it easier for me to be around his family.Why can’t this be fun? I have the same control issues with my brothers: I want them to behave a certain way around my mother to make it easier for me and it has led to me not seeing them.
So if I think that this is about him and not about me, it still feels like I am giving him a pass to behave however he wants and then I have to clean up. His daughter really is nice and the grandson isn’t the worst (though he can push a remarkable number of buttons!). I still need a lot of work about taking responsibility for others and trying to ‘fix’ everything and control it all. I honestly don’t know why this kid makes us so crazy, I feel like I have already failed.
I did a few models to work out the stress but not sure I am getting anywhere, I can’t seem to have a conclusion that feels true other than I am a bad person, which is frustrating because I was trying to do something good 🙁
