I have a friend who has an adult son with Asperger's and when he’s not depressed I feel a real connection and calm when I’m with him. My late husband, as I mentioned, may very well have had schizoid PD. I had somewhat more passion than him but that kind of emotion was usually frozen or turned codependently toward him. Most of the time, though, we got along very well in the unemotional “calm”. (I did feel love and loyalty from him, though.)

Very good point.
