Polar bear is right, You can't even be friends with this guy, they see friendships as a means to an end and even use their friends to get what they want so even if you be friends with him he will use stuff against you. I was in a relationship with a guy who has sociopathic traits for 5 months last year. End result - he put me in the hospital. Literally, for several hours. I freaked out when he told me he moved in with his next victim - er, now gf in only a week after breaking up with me....these guys have very shallow emotions and have no problem detaching as quickly as they attached to you. I took out my anger on stuff around the house breaking stuff up, my parents called the cops on me, i said i wanted to kill myself, and the cops took me to the mental nhospital where i stayed for a few hours where no one asked me anything except stupid questions like what year is it and whether I heard voices. My parents were no help as they are of the belief of 'just get over it' Luckily I dont have to see him as the guy has his own dojo and now trains elsewhere far away from me and i dont see him or his now victim (who i talk to sometimes but not very often, he will get her to believe he's ok and so will not defend me either) so i dont talk much to her on fb) I'm still onProzac because of my depression.
Intelligence has squat all to do with it, or what degree you got. These peeps are so good at what they do they can get anyone. so dont beat yourself up over it.
advice from The Blade (me lol):
Don't try to make nice with him.
Dont even be his friend.
Do let your boss know.
Dont be alone with him.
Only work with him cause you got to but dont see him outside of work, on breaks around the watercooler, etc.
Only time I'll have to see my abuser is at karate seminars and tournaments. But i can just stay the hell away from him.
