DH finally had "the talk" with MIL.
Well he finally did it. She kept pushing for a "discussion" on how she wants the next visit to go. How upset she was with us for moving her things and how she was in charge (after she asked us to move her things and how we did exactly what she asked.) she was upset with him for throwing away a box of open sand that was leaking. She expected us to measure it out into mason jars. A 50lb box of sand. She was also upset because of the boxes that were stored above her head, at the height they were previously stored in. That this is her life and how she wants to run things is how it needs to go. So he told her that the next visit we would be getting an air BNB so we could focus more on spending quality time with her. That we would not be spending the entirety of the visit reorganizing her hoard and fighting with her. If she would like to keep her living environment the way it is we respect that, but we will not be contributing to enabling her unhealthy living situation. We would not be arguing with her over her medical care and that if she believes she is fully capable of organizing things then she can retain control. He told her he wanted to instead focus on spending quality time with her while she's still with us. She didn't like that at all and started to argue with him how she needs his help. He told her he was not going to spend visits fighting over her living conditions and that we would not be subjecting ourselves to the same. She has more than enough income to hire help as she sees fit. That he wasn't going to subject himself physically and emotionally to the conditions she chooses to exist in. If she wants to keep a relationship with him this is it. She said she needed time to think about her answer and they ended the conversation.
He was decompressing from their discussion and I told him how her answer defines how she sees him. If she decides to pull the plug on their contact because of this, it shows him she only sees him as a dispensable asset to do what she wants and that she was never interested in genuine quality time with him. He realized that the minute she started arguing with him.
Overall, I feel relieved he finally had the talk with her. But my heart also breaks because my husband is realizing he's never had a parental relationship with her.
It's just sad all around. But we refuse to continue to fight her on her situation. The state has stepped in and that's pretty much as much as we can handle.
