I am sorry you are still going through this. He is so obsessed with her, and I can't imagine why. She sounds horrible. He shouldn't love her or hate her, he needs to be indifferent (to know you are finally home-free on this issue). I wish you both could get different jobs!
Not to mention, isn't he like a therapist at your work? And wouldn't it be against the rules (and ethics) to be going into other email accounts?
And before you go to that guys wife, I personally would go to the guy and discuss this (letting him know that he should stay with his wife, and that Monster is trouble). If he doesn't listen, you should go to the W.
