Does he still have a sizable stash of alcohol hidden in a closet? Don't keep your purse or any money in the residence you share with him, from now until you do leave. Change the pin numbers on your accounts, and, if you even suspect he has access to your personal papers/bills with bank or credit numbers on them, chances are he does, and he has or will make note of/recorded them, consider closing existing accounts and opening new ones.
Can you be sure he has not taken blank checks from your checkbook?
It will be even easier for him to raise funds with info he has gotten about your accounts, when he doesn't see you everyday, and his financial circumstances have grown even worse than they are now. Do not lend him money to pay the rent after you've suddenly left him to pay the whole amount by himself. He will ask you to.....
Does he have a set of keys to your car? If you are sure he does not, lock your purse in a hidden location in your car, the moment you arrive at the residence that you share with him.
Get out now, unless your strategy is to make yourself a target for him to assault, so you can file a complaint for the police to remove him, then get a restraining order, than try to get it enforced....blah, blah, blah..... get out of there by the end of the 4th of July weekend.
