Positive is great! Don't let the positivity get ahead of you and turn into expectations, which are just resentments waiting to happen.
Encouragement is great! Don't let the encouraging turn into pointing out his recovery path or walking it for him though. Restating what I suggested in my last post (on another thread), get and read recovery books for you, not recovery ones for him. Get him an unrelated funny book, one about a possible hobby interest of his, some book on his cart or wish list, anything but a recovery or addiction book.
Recovery is an inside job; his job. Let go of that. Let him do his job. If he succeeds, it's only going to be because he did it from the inside out.
