His alcoholism will get worse as long as he's tipping the bottle. If he's at your house and not drinking, he'll start if you keep him around. He will not take your feelings into consideration just like he didn't when he stole money off of you and your kids. He will learn to be a better liar. He will bathe in after shave and drink more mouth wash to cover it up. He will do what it takes to keep you as his enabler and get what he needs to continue on with his alcoholism. He will suck the life right out of you.
