Sounds like he doesn't mind assisting financially in hopes of in the end seeing you grow to become financially independant, take it as motivation to get out of the hole you're in and come out THRIVING!
The important thing as stated is communication. Also you are trying. That is also important. My DD makes depending on the year 10X to 15X what her husband does. He refuses to work anything but part time and considers all his pay his personal mad money. She gets stuck with every bill. He refused to take an upgrade at his job to full time which would then lead to a promotion and doubleing his hourly pay. She is in upper management of a major firm. She is now trying to find to find a way to rid herself of him without paying alimony. Until then she feels stuck.
