This sounds so over the top to me that I think I'd be a bit concerned for my own safety. Seriously, this is insane behavior on his part. I haven't followed all your threads in detail, but I think in your shoes, I'd be considering some way to become invisible to him. There is no reason that I can see for there to be any contact.
Maybe the folks w/DV experience could chime in; maybe I'm over-reacting.
