This man is in love with me, but he is a narcissist. I have no intention of dating him, I made that perfectly clear. He makes me miserable, depressed and feel trapped. He tells me I am stupid, ugly, fat etc and that no one wants me and that he is the only one in the world who could love me. He tells me if I stop talking to him he's going to commit suicide and blame it on me, he manipulates my friends and they shout at me if I ignore his messages. What do I do? Help!
