I am so sorry for your pain, Vaya. It is heartbreaking to see them in such a sad and desperate condition.
I wonder why you say he can't be in recovery or in treatment on methadone? Some of the outpatient clinics are very amenable to methadone, and folks at AA/NA meetings don't need to know/don't care if he is on methadone. Just curious.
Keeping you both in my prayers.
