Going crazy!!!

I met a boy online. We used to chat daily. We became very close and soon started ted dating. We loved each other a lot. But slowly he used to text very less and i would sometimes get mad at him. He said he had work nd could not text me all day. I understood that but i wanted atleast some amount of his time which was slowly going. He said he had started losing feelings for me because i kinda choked him. I promised i would not do so. But he was adamant. I pleaded a lot. He said he needed time. For two days i waited. It was the most frustating time for me. It was killing and painful. I loved him a lot and could not bear the words he had uttered that he did not feel for me anymore. After two days he said he wanted us to be just friends. I called him a bunch of times after that text but he refused to talk and threatened to block me if i called again. He pushed me to the limit where i lost my patience and cursed him.i said a few offensive things in anger. He turned against me after that and blocked me. I sent email apologizing but he said that i went off the limit and that i should just "fuck off". A week later i come to know he is dating a friend of mine. This friend and i had, both of us had met him online. He was real good friends with both of us. This friend did not know about our relationship as he asked me not to tell others about it for the time being. I told her about our relation and regarding our fight. She refused to believe me and said she knew from a long time who "liked" whom. (Implying that it was just me who liked him whreas he liked her). She said they were dating each other. I was shocked and shattered. Not even a week had passed before he broke up with me and he had already started dating someone else. I accused him of doubledating as i thought he did that. But he said he did not do so. And he said he did not feel that i deserved an explanation as to why he had started dating her. He used phrases like.."She is very close to me and you aren't" and "if u try to spoil her life..i will make ur life hell". Those words hurted like hell. I never wanted to lose him and i was not even over him yet. And he simply hated me. A lot of namecalling nd cussing ensued. He is no longer with me. And i know things will never be back to normal again. Though i should hate him. .i simply feel miserable. I just can't bear the fact that he is no longer with me,he is in love with someone else and that also so soon. Plus he hates me and thinks i am a bitch. There is a sort of emptyness. I really miss that person who used to love me and meant the world to me and maybe i meant the same to him at some point of time. It just sucks.
