I think it's time for a separation. You don't have to go immediately to a divorce, but I think a separation from him for a time should send a strong message. Let him know you won't put up with this, he needs help, and you're leaving until things improve. Ask a friend if you can bunk with them for a month or so. Start separating money. You may need to figure out how to survive on your own...because if you do divorce, you will have to anyway.
