Yada Yada Yada....
Listen! His recovery is HIS recovery. DO NOT let him pull you into his issues. What's he trying to do? Make you feel guilty so he can feel better about himself? Give me a break.
I know you are trying and I don't want to come off as being snarky but I think it's probably time for you to disconnect from HIS recovery. You work on yours..let him work on his. Please don't feed into it..
