I feel for you. I’ve been in that situation for over 20 years....and I’m at the end of it. I only stayed in because of our children, both are now adults. If I had to do it over, I would have left him/had him leave to stay away (it was always about finances not love).
It might be tough but move on from him. You deserve better.
