If he stopped going to meetings because he didn't get the reaction he wanted out of you, then it was just a matter of time before he stopped going anyway.
I'm saying that from experience. My ex is a skillful manipulator and made everyone in his rehab clinic think he was a model addict-in-recovery. Until he understood that there was absolutely nothing he could do, ever, to make me come back. Then he started drinking again.
I refuse to take responsibility for that. I'm glad you're realizing that his recovery is his own, and that yours is your responsibility.
