FWIW, my T subs under someone who is doing a pile of research on narcissists and PDs. She's had discussions with him about my case because it's very clear that the H and his PD psycho g/f are a toxic soup of one needing to feed off the other.

It's not about excusing his behavior, only allowing me to understand it, so I know how to best protect myself and utilize what might be unconventional methods. (Eg, back rubs.)
