I've noticed that you often swing back and forth between saying how selfish and awful he is to you, and then how helpless and unable to care for himself he is. You want him OUT when he is being selfish and horrible, but you weaken when you think of him as helpless.
They are both sorta correct, in a way, but they are just facets of his behavior and personality that are screwed up by his alcoholism. Both would be drastically improved by recovery. Alcoholics are complicated people.
You don't have to wait until you are angry to put him out. In fact, I think it might be better if you do it when you AREN'T angry. If you do it when you are calm, and do it with love (even if he is raging at you), neither of you will have to feel that you put him out because you can't stand him.
I'm not sure what I'm trying to say here, but do you get what I'm saying? If you made a plan for him to get out and insisted upon it, no matter what he says or does, and you don't lose it, yourself, no matter what he says or does, you might actually be able to follow through with it.
Because it wouldn't be done out of anger.
Does that make any sense?
