Wendy, When you h attempts to draw you into discussions about financials, either change the subject or walk away. You are now at the point where these type of discussions should be held in mediation. All he is doing is trying to beat you down to submission so that you will agree with what he wants. Don't go there.
Walk away from him when he starts this nonsense...it's not good for you.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
