Is he violent? Are you afraid of him as well as financially and essentially otherwise controlled by him? You can call 1-800-799-7233 or text START to 88788 for help with domestic abuse, which I believe this is? He has sole control over the money, IE all the resources. Why?
I ask because this riles me up and I’m worried about you. Good luck. Text that number if you have a phone that he doesn’t completely control.
