Here's my 2c. You say he's a control freak about money and indecisive. I am not going to defend him with my next statement. I'm just going to tell you a little about myself and see if anything clicks with your sitch.
I was also considered (still am by W?) to be money mad. What I saw at the time was being careful. Times are tough. I thought I was doing a great job because no money = no life. Not true but you get the idea. My W says she had to ask for everything - also not true from my perspective but it was from hers. Get what I'm trying to say?
The indecisiveness bit could be that he's thinking about a gazzilion things at once (just like you) and not being able to concentrate on the important ones. Blokes are no good at multi-tasking - you girls are (lucky you).
You are not responsible for this. This is maybe why you feel him to be so distant. He's trying to process.
The part about who should actually file gives me hope. It doesn't look like either of you want this to happen. The plan now is how to move on to breathing a bit more life back into the M.
Any ideas from your side with the steps you would like to take and the response's you'd like to see?
Chin up - wonderful day is on the way to you and yours.
