I am reasonably certain that my ex-boyfriend is a narcissist, I ve read about the personality disorder and it described him to a T. I broke up with him several months ago and he can t seem to leave me alone. I ve had to block him from contacting me but we still work at the same company. He was harassing me and after my boss told him to stop or be fired, he has switched to passive aggressive actions. It s like he has to get a reaction out of me and doesn t like it when I ignore him. What else can I do to get him to leave me alone? How do you deal with a narcissist? I feel like I ve tried every way to deal with him and the situation but nothing has worked for me, at least not for long.
