Victims of Psychopaths Community Group
Is he or she a sociopath or psychopath? Think we're only talking about serial killers here? Psychopaths, sociopaths and even narcissists come in every walk of life, every career level, and every socio-economic category.
It isn't about your friend. It is about the fact that he KNOWS that she will tell you, and it will get to you. it is deliberate action on his part to get to you, and it is working.
Can you ask your friend to contact him, say she doesn't want to hear from him. Stop contacting her. And ask your friend, if she could not tell you. He is doing this deliberately to get to you.
