Be thankful that he is not contacting you! However, keep your guard up, because he just might surprise you when you are least expecting it.

Hopefully he is hooked up with someone else and he is now someone else's problem,. I feel for that woman tho! May she have strength to leave him.

I not only see NPD in your description , but I also see sociopathic traits as well. This is very, very dangerous and my advice for you is to let go completely. Count your lucky stars he is leaving you alone and not attempting to use that "switch" on you. I am very well aware of this tactic, that is why I say keep your guard up because he may very well show up again in your life unexpectedly.

I would change your phone number and change your email accounts. Make it nearly impossible for him to get a hold of you.

Guard yourself . You are lucky to have gotten away as soon as you did.
