I'm bipolar & have antisocial personality disorder/probable type 2 psychopathy. From his behaviour? I'd say it's probably very, very, very severe mania with probable breaks from reality. While he may or may not have ASPD, sadistic PD, or just be a normal person; there is something very clearly not connecting in his mind between his thoughts & his actions. If you haven't left already, you're not doing yourself any justice whatsoever. Not everyone with psychopathy is a violent, incontrovertible asshole... At this point, it doesn't really matter what he is. Just that he's gone & possibly gets help. Maybe once you've made plans to leave, if he pulls another stunt, you could privately call the cops to get him baker acted & the proper help he needs?
