If I were in your shoes, I would cease trying to communicate w/him about anything except the children. Evidently he is living in La La Land whereby the fairies sprinkle fairy dust and poof! All financial issues are gone.
You have gone above and beyond trying to reason w/someone who is definitely not rational at all. Again, please stop trying to reason w/him....you can't. The best you can do is pay the man off and let him go totally.
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.
