Wow, I feel OP is holding a mirror. I go out to watch a movie, stare at the beach, gym, or even just play games on my phone in my car. Makes my WAW uneasy. And my WAW has her entire post D planned too. Except for the fact that the house hasn't sold, and she's convinced that I will accept whatever financial demand she asks "for the sake of the kids." I said the same thing that it might not look as she planned.
The act of stepping up to enforce boundaries is a good shock. You may find her protests disminsh each time you do.
