What's up with the narcissist posts lately? Did a book just come out or something? A TED talk? Is Sam Vaknin at it again?

Anyway, he could be a narcissist or one of the other Cluster B PDs, as a lot of those traits overlap. He could simply be depressed or have commitment issues. It's difficult to determine without being able to speak with him directly to know what exactly was going on in his mind when he made these decisions. Regardless, he definitely seems emotionally unstable, and I think you're right to avoid a relationship with him.

I disagree with the therapist about him changing. But he's 56, so why bother trying?
