You do realize that you don't owe him ANY support during his recovery, don't you? That's not your job or your responsibility. That's ALL on HIM. He has to want to get sober for himself with or without you. Your support has nothing to do with it. In fact, in many ways it's a hindrance because the alcoholic/addict comes to rely on it and expect it as if it's something owed to them. That's not reality or real life. My advice would truly be to run and don't look back. Let him figure his crud out on his own and spend your energy on yourself and your child. You owe him nothing. Just my two cents.
