RTL,
You are doing the best thing by not responding. Your W sounds like she is cornered and lashing out. She sounds angry at her situation and is threatening you.She wants to scare you, so don't let her. Maybe she thinks if she can't get things her way through the legal system, she will do it by intimidating you. The best thing to do no matter how difficult is ignore. Try not to give her any fuel for her fire, it sounds like she is having a fit because maybe the evalutaion is not going her way.
