Carrol, I'm so sorry you're having to deal with this. I think I would feel just as paranoid as you seem to be, and I think you have reason to. Like bluekoi said, you probably have some difficult decisions to make, but at the very least, do not allow him to brow-beat (verbally abuse) you...his actions are very troubling and you have reason, IMO, to be concerned.

I hope things work out for you
