Hi, bmd.
If we could love someone into recovery, this site wouldn’t exist.
Sadly, we can’t.
I could be wrong, and this is my opinion only, but I’m sensing a kind of rescue vibe here.
It’s good that you feel you can provide a safe haven for him, but....
End of the day, that doesn’t matter one bit. In fact, it’s not wonderfully helpful for either one of you.
Saying this gently: He will continue to use, and to use you, as long as you allow it.
Peace.
