Nothing good can come from confronting OM or his W. It won't give him the closure he needs. The only reason in my mind to ever contact OM or OMW is stop on ongoing A. Now that's over by your admission; he should leave it alone.
That's my opinion. But you can't control him. I just don't think he's going to like the reaction from you once he crosses this line.
I find it interesting the fact that you shut down before you have a friend get close. My W always said that she had trouble keeping girlfriends; that's why she chose to have guy friends. Trouble is, her guy friends....well you know!!
Good Night Max. It's late for me. gotta sleep and get kids off to school in the morning.
