I seriously doubt that your xh has come out the other side yet. If he's still displaying confusion, etc., it sounds like he's still in depression and needs some assistance in the way of ADs.
His brain hasn't quite gotten settled down and he's really having a difficult time with numbers, etc. Do you know if he had issues with math as a teenager?
It appears you are going to have to work on his math issues for him in order to get what you need to support you and your children. He's truly still out there in some areas.
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.
