mama...this man is dangerous. I know you're not in a position to cut contact off completely (yet) but document EVERYTHING. Heck, place a little tape recorder near the computer desk to record the conversations and transcribe later if needed.
My XAH was a narcissist and ...a bunch of other things I can't put my finger on (delusions about the apocalypse, about him being a superior being, about his son being the new messiah, etc). He put himself in a position of not seeing our child and I didn't do a thing to stop it. Now he doesn't see her at all and I'm glad for it.
