I would have a talk with his wife again. Is she really being that naieve and trusting STILL?
Have you TOLD his wife that your wife wanted to divorce you for him and admitted she's in love with him?
I want to know why his wife is still comfortable with her husband talking to a woman who claims to be in love with him.
What wife in their right mind would sign off on her husband talking in private to a woman who claims to be in love with him?
I suspect you haven't told her about that. If not - EXPOSE the affair properly... don't pull punches.
If the OM tells you he will stop and he's emailing her again a week later you need to find some leverage on him.
Does he work? Show up at his workplace in front of EVERYONE there and humiliate him. Call him a creep and tell him to stay away from your wife or you're coming back and you wont' be nice about it next time.
This guy is just humouring you. You need to find a way to FORCE him to leave her alone.
I would not try to intercept messages. He has to WANT to leave her alone...
If you have a way to transparently trap incoming mail and COPY it to your PC then do it... it is valuable intelligence.
IF your wife will discover this, don't do it.
Your wife IS having an affair with her Ken.
If SHE refuses to end contact, AND he is ignoring you, that means they are putting each other before you... that's a big RED LIGHT.
Get his wife involved... she HAS to apply pressure on his end.
