I wouldn't relay on him paying your vehicle gas bill any longer. Why? Because he advised you to get your own separate account to take care of your needs and I believe you did that. In the future, before you use the "old" account, you might want to think about setting up your own account for your vehicle's needs. I don't think your h is going to be inclined to continue to pay your bills, especially if he's already giving you a monthly allowance, small as it is.
Sounds to me like he's only putting enough into that account now to pay the mortgage. Sorry it's getting tight when it comes to money w/him...but he's really trying to cut all ties and doesn't want to be responsible for any monetary things w/the family. Yes, he told his daughter to come to him if she needed money...but where's he going to get the money if wages are being garnished and he's got over due bills all over the place? When he told his daughter to come to him, most likely had money...but now reality is setting in and he is moving further into the replay tunnel of the "me, me, me" song.
You'll know when to advise your h that you've seen a lawyer and provided the info as requested. It's not a fun trip, but you have to do something to protect yourself and what's left of the assets. It's not what you wanted and I'm sorry that it's come to this. But, Ambivalent, when you get the financials settled, things may look a bit better and you'll know where you stand as to allowances, etc. Right now, it looks bleak, but it won't stay that way forever.
I know you don't want to lose the house, but you need to have a contingency plan in case you do have to move. We all have had to come up with different scenarios to help us if Plan A or B doesn't work. I would hate to see you caught unawares if something should happen down the pike.
I do hope that you are staying warm and your little fur babies are there w/you today. I'm glad your daughter is visiting and who knows...she may be able to offer up some support to you today.
Hang in there!
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.
