Yes, I’ve read about betrayal trauma.

I spoke to my lawyer

She said, “That’s easily traceable. And you agreed to the new mortgage rate, signed it, then she went to the bank in person and blocked the mortgage renewal. There is no possible way her legal counsel advised her to do that. Her counsel will probably tell her to put it all back and sign the mortgage before court, which is two months away. If she’s refusing to listen to her legal counsel then we’re just dealing with chaotic behaviour and that also isn’t going to play out well for her .”
