Just reading up on your post. Wow. Lots of heavy stuff going on for you. I would try to be as supportive as you can of your H right now. Sounds like he is in a very bad place with losing his job and in a bad place financially otherwise. Try to keep supporting him during this rough time. You want him to see you as a friend and ally. Show him that you are trust worthy and that you are not going to disappear again. Hopefully this will help him trust you again.
