Ignore him
Counting his blessings. He's not late yet.
Tell him he's bring this upon himself and that you're feed up with the "poor me" routine. He's what associates call a "sympathy whore". Don't afford him anymore sympathy. It's called "tough love".
Good luck!
Have you told HIM you're tired of it? Be serene but straight-forward and tell him that you're within to help. If he can't back himself and continues to belly ache nearly things, let him know that the "help" will for good stop until he does something for himself.
