A family member of mine has been diagnosed with ASPD. We get along ok, but I know him, obviously. I understand him, I should say. We get along ok.

He is good at making "friends" and acquaintances but generally doesn't play nice with others, regardless of psychiatric label or lack thereof. I guess it's most accurate to say that he's not one for long term relationships or friendships. At some point, he's finished and has no compunction moving on immediately. Some people are shocked, others not so much. Depends on why he was hanging out with them in the first place. He keeps the end game in mind.

He doesn't hang out with other ASPD's unless it's for a very specific purpose and the common psych label would be a coincidence. It's not a companionship, it's a common goal that is short-lived. He'd probably get into a fight if he regularly interacted with another ASPD, I think. He has an aggressive streak, he does not feel fear, and he gets very defensive if confronted. I love him and he cares about me in his way.
