Hey Life. Have you thought of it this way? His words are not consistent with his actions. That doesn't foster trust.
Does he mean what he says? Likely at that moment in time he does. Will he take action on them? Not if you pursue. Not if he doesn't have to, he won't. He recognizes things, but doesn't seem to have hit bottom. He won't if you are there to catch him. You are not quite there, but you're not quite gone either. Understandable, but not very productive or positive for you either.
Give yourself permission to let go and let him work himself out. If you don't you might get somebody who looks like him but isn't. He needs to complete his journey else you have nothing. Like something out of a S King novel, right?
No action for you right now towards him. Lots of action for you and towards you. Work on you right now and let things be where it concerns him.
