This is abuse, leave. Take the dogs for a walk, go to a friend’s house and call a lawyer or the cops or a womens’ agency. Yes everything will be shit for awhile, get a restraining order and file for legal relief from the debt, you may even be able to sue him for relief of the debt, and if he used your credit without your ok, that is fraud and also illegal.

I know you feel you don’t have the mental strength to leave but if you can survive staying, you definitely do have the strength.
