Perv did this also. He went into hiding while responsible for overdue bills and would not respond to inquires for a long time.
People actually thought he had died, but he was in hiding trying to figure out how to end his marriage.
It took some time for me, but I was in the same way of thinking as you. Your WH has moved on in his life and you are, unfortunately, left to fend for yourself. what I learned the hard way was that communicating with him directly would get me absolutely nowhere.
What I and some fellow local BS did was to contact places like utility companies where bills would be pending and tell the situation. As well, we asked for documentation from each for what our rights were and also we asked for things like minimum balances due.
Another thing we did was to change things like bank accounts to take the WH name off it because we didn't know the frame of mind or what they would do next. Anything shared, we made single, for security's sake.
It's time to look out for #1, you, first and foremost. It also helped keep busy, buy calling the businesses and it helped me feel more in control of a hard situation. Also, for the business, they backed off if things were late and knew someone was trying to work on it.
I'm sorry...security isn't to be had when this happens, but we can get it back with action.
