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.
Lol. Happened just a few weeks ago, when I had to leave a group in my seminar at uni because the group wanted the guy they were with the week before and it was easy to get rid of me because I was the newbie. I understood where they came from, but it still hurt like a bitch and made me a little bit self-destructive.
