How can i get over my first love?

i was dating this guy for four months. i am 14 and he was 16. he told me he loved me every day, and how much i meant to him. he told me i was the most precious thing to him that i was his only reason for living. he was born with some problems with his hands and only had 6 fingers. people made fun of him all the time but i didn't care. He was sweet gorgeous, and the best thing of my life. we were going on strong. but then a couple friends told me he was ting this new girl who had just came to our school. She was GORGEOUS. i was really upset by the thought and i came to him with tears in my eyes and asked him about it. he told me he didn't do it and i believed him. then on the day of our 4 month anniversary together he dumped me. he did it by text, first he said we just needed a break. i told him it was killing me not to be with him but i understood what he wanted. Then i never heard back from him. i tried talking to him in person but he blew me off. so i called him that night and he didn't answer. so i texted him. this is when he told me i was too clingy, i made him mad all the time, and then he said that everything he ever told me were lies. everthing about how beautiful and amazing i was, and that he only said those things to make me happy. i don't know how to get over him. everyday at school he laughs at me for being so upset about this whole thing. he calls me a skank and slut everyday. I love him so much but i just can't find it in myself to get over him. i can see how much he hurt me and that i never mattered to him. and the sad thing is that his version of clingy is everytime i say him, i would come to him and talk to him, then when i would see him at basketball games and other school sporting events i came and talked to him. one time he told me to go away. i thought he was kidding, so i said wow i feel loved. Then he told me to go away that he would come love me after the game..... i am so heartbroken, my friends have given up on me and i just fell awful. How can i get over him??
