Shame I knew one just like that :-( And I always wondered why such a beautiful person was single. One learns from difficult situation :-( Common Symptoms of Sociopathic Personality Disorder - wow! Lying and having no remorse or guilt. What a sad, miserable life.
If you are being abused and you determine that your 'partner' has the symptoms of psychopathy, stop blaming yourself. Consider that the abuse in combination with the signs of psychopathy means you are likely in a relationship with someone who is dangerous to you.
