Unfortunately, it does sound like he's headed back down that road. There's nothing you can do to help him until he wants recovery. I'm sure you know that. He isn't ready yet to change. Until he is so miserable he cannot stand it another minute, he won't change. Giving him a home with all that entails is keeping him from hitting his bottom. I know it's hard; I've been there, but it's what has to be done if you want any kind of peace and serenity in your own life.
