Sorry to hear about your sitch 1313. I do not know what state you live in so despite being an attorney, cannot give any legal advice. Sounds like you are already getting it though. I will say I do not think you are able to share any emails from her to her lawyers, with your attorneys. Before you show them anything, tell them what you are about to show them first so they can tell you whether it would breach an ethical standard.
As far as your WW, I would recommend you read and reread Sandi's rules and Sandi's reflections. Then tailor it to your specific sitch. I have found tons of good info in there. Mainly the giving space and detaching. Remember don't believe anything she says and 50% of what she does. If you asked my WW I am gay and my lack of having sex with her drove her to this. Its funny how history is rewritten because I remember things very much different. After reading Sandi's posts I think their verbal attacks are a way of showing you, they have lost all respect for you. I also think its a way to deal with the guilt.
Good luck to you! There are a lot more insightful people, than me, on this board that can help you!
