i have been dating this guy for a year. for the past one year we have being dating, all he did was to criticize every man i had dated and finding means of talking to them about me. He succeeded in driving all my male and female friends away from me, because he said am not truthful and all the men i dated never loved me, but dated me because i was available. he calls me names at the least provocation and blackmails me when he feels threatened. he even posted some nude pix of me on some websites, but the fact of it all is I love this guy so much. he said i never came up to tell him about my sexual life. when i gather the courage to leave, he persuades me to come back, but now, he has broken up with me without any cause. what do i do?
