I registered to tell you this:
I dated a man with ASPD. He was well regarded by friends. He would lie to my face without a flicker of guilt and tell really extravagant fibs to cover his deceptions, weaving complex webs I could never totally unpick.
He had 2 secret children he didn't support. Or maybe he didn't have them. He told me he had them but I never saw a photo or any evidence, so he could have invented them so he would seem more human. I will never know.
Cheated on me constantly and when confronted with the evidence (texts), faked an episode of PTSD to distract me.
Strongly hinted he was abused at boarding school, but only ever mentioned it when I was confronting him with something he had done. Also claimed to have witnessed a friend commit suicide, but I have no evidence this ever happened.
He used to pretend to cry. One day I pulled his hand away and noticed he had no tears. I told him he was faking it and he smirked and said "I know", then went back to watching TV.
Was obsessed with porn and gradually manipulated me into more extreme sexual acts because nothing else stimulated him. When I left him he had suggested I have set with a dog and tried to convince me to become a prostitute and bring men home to the house so he could watch.
He brought ex girlfriends to the house and slept with them then denied they were ever there, despite me seeing them with my own eyes.
Personality disorders are not like being diagnosed with anxiety. They are not mental health conditions in the same way a mood disorder is a mental health condition.
They are deep rooted problems with a person's entirely personality and essentially their soul. People with BPD can recover if they honestly engage with DBT but no therapy exists that can rehabilitate ASPD. All therapies that have been tried have just produced more skilled sociopaths, teaching them how to fake empathy and impersonate the emotions of normal people.
It is not a sexy, intriguing disorder. People with ASPD can't love, can barely feel. To say so is not "stigma"; these qualities must be present for the diagnosis.
You cannot fix this man. No one can fix this man. If you are too lovestruck to think straight, think of your kids. Playing with fire sounds exciting until you burn yourself.
