I'm friends w/ his W as well -- well more like acquaintenances, but if he keeps it up, I might just call her and see if she wants to go to lunch some time. We work really close to each other and had talked about it before. That would wake him up. Of course, I'm not going to say anything to his W, but it would probably scare him a lot thinking I could be telling her things.
That sounds to me like you're getting mentally sucked into a "game" with him. Don't aim at getting any sort of a reaction out of him. Just route all messages from his address into a special folder that you'll only open up if you need evidence of what he sent you, and carry on as if he didn't exist. Hang out with his wife or not as you please, for your own reasons.
a fine and enviable madness, this delusion that all questions have answers, and nothing is beyond the reach of a strong left arm.
