Dating a sociopath- hopeless?

, I’ve been seeing a guy who says he’s a sociopath and feels nothing for anyone except his son. BUT he abandoned his son and wife (not sure if they’re still married?) to move to California 3000 miles away, for a job that’s not much different from his job back home. He’ll tell me he’s so depressed over missing his son and “ruining his family,” yet he could’ve gone back home for the last 4 years and keeps choosing not to. He wants to be left alone bc he’s depressed over only seeing his son every few months. But then why does he not move back home? He told me if he could leave his family then he could leave anyone (such as me) with no remorse. So is there really any way for me to make a relationship work w him? He’s certainly very interested in sex with me... but when I say I don’t just want cold emotionless sex where I feel like I’m being used, suddenly he doesn’t wish to see me at all. At one point he said he needed a therapist before things “got too bad” and has family history of schizophrenia. Then when I brought up the therapist he looked at me blankly and said he never said that.

Why bother with a guy who feels sorry for himself and someone who can't/won't help themselves and how can you date someone successfully, who's not going to return anything to you, regardless of how they classify themselves. You need a guy who doesn't use you for sex and a guy who at least has respect for himself. You'll end up being his personal counsellor and being dragged down to his level where, incidentally, he wants to be.
