I wouldn't make it a habit to go to meetings with him, but I don't think it hurts to go to one here and there.
I can always peg the people who come in with their spouse clutching their hand and figure they won't be long for the program. Recovery involves a lot of work one oneself, and it's pretty difficult to do when you've got your significant other right there with you.
If I were you, I'd wait a few weeks before going to one with him. He needs to go without a "prop." You can certainly learn a lot at meetings, but if you want to learn about AA I'd go to a separate open meeting without him.
