Well, your last posting says a lot about your h. He's passive-aggressive, he was stunted emotionally by his family, his father has died, he joined the military, he's been divorced. He is very much ripe for a mlc.
Can you stall signing the papers? Do you agree w/what he's got in them?
All you can do is be a friend to him right now. His head, heart and soul are very screwed up and he does have a lot of unresolved issues from his childhood that have carried over into his adult life. No more talks about the relationship/marriage. If you can avoid talks about the divorce, then do so.
I'm very sorry you are here. He's a train running out of control emotionally.
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.
