The reason I ask is, IF what you say about him being afraid of his wife is true (and this would be very typical for a cheating male, to NOT risk his own marriage over his affair girlfriend), and IF this is also a case of "unrequited love," then you may want to approach the guy directly, perhaps even bluffing that you have something on him. Or better yet, start with his wife. He just MIGHT finger your wife (sorry for the phrase) as the one who's batchit crazy/bunny-boiling here, and IF you could get him to do a "Look, I told you, I'm NOT leaving my wife over you, so get that thru your crazy head!" . . . well, that would kill it dead in its tracks.
