Sociopathy, also known as antisocial personality disorder, is defined by the Mayo Clinic as: "a mental disorder in which a person consistently shows no regard for right and wrong and ignores the rights and feelings of others. People with antisocial personality disorder tend to antagonize, manipulate or treat others harshly or with callous indifference. They show no guilt or remorse for their behavior."
Though we may all be quick to label one or more of our exes a sociopath, it's a real clinical diagnosis. And people who've dated or married someone with the disorder often experience long-term emotional and psychological scars. Someone asked Reddit: "have you ever been “romantically” involved with a sociopath(ASPD diagnosed)? If so, is it actually a traumatising experience? What is it like?"
