It is his disease to own; please let him own it. Don't attempt to control, don't micromanage, and don't enable. If he wants to talk about it, let him, but don't push and don't pretend to have any answers. Encourage him to find his own answers.
It really might be a good idea to contact your therapist again, and check out a few Alanon meetings, or at least the steps. If you're both working the steps, you're both on the same page. If he's working a different recovery program find out what the equivalent is for loved ones.
Best wishes to you and yours
