Color me shocked on the moving thing. I knew she wouldn't actually move. It was a pipedream
RR, good job on the 180. That sounds huge. I am also stuck on how to set a boundary on that. I almost would say just let it lie for now. Maybe it was a one off incident and she won't repeat. If it does happen again, then that will give you the opportunity to say something like "please do not speak to me in that fashion. I am sorry you are upset, and I will gladly discuss it with you rationally when you can do so civilly." Be calm and friendly when you say it.
Hopefully someone else will weigh in with better advice.
"Well, May came and went and W didn't move out nor did she show any signs of movement in that direction. Not until last night, but I'll get back to this."
Did she address this in her ranting over the spending? I don't see where you got back to the subject of her moving out.
