Go to the meetings, yes? Your new friend sounds knowledgable, supportive, and kind. Your husband may be the rare case where he doesn't need a formal recovery program and never relapses but it doesn't sound like he's all that great to live with sober and it really doesn't sound like he's made much progress on giving up an addict's selfishness.
Knowledge is power. Go to the meetings and learn from others who have been where you are. That way you will be prepared no matter what happens.
P.S. Was it really "great"? Or were you just going along because he insisted? And then he insulted you. Not nice.
