I agree with the previous posters.
What is there to gain for you by having contact with him?
Are you willing to risk your hard-earned emotional equilibrium for whatever you might get out of it?
In the interest of full disclosure, I find that every time I have to have contact with AXH, it pushes me a little off-center again, and I have to take deep breaths and go to a few meetings before I'm myself again. So that's where I'm coming from.
