I have no idea what to do about this whole thing.

I lost my virginity last weekend. Im fifteen and hes seventeen. We had been seeing each other for about a month, but we werent anything official. He told me he wanted a relationship and so did I, and i guess i thought we both really liked each other so i gave up my virginity to him. two days later he texted me and called everything off. said he was sorry but he didnt want a relationship right now. now every day he talks to my best friend and today me and him got in a fight and he called me fat, easy, and a whore. I keep telling myself i dont like him anymore but the truth is i do and i think about him all the time. i dont know what to do anymore and fighting with him isnt doing anything, but i dont feel like i can move on. I will never trust anyone again in my life. i feel so disapointed in myself that i gave my virginity to someone that ended up being a complete asshole and just using me for sex. i literaly feel so alone and like i made a huge fool of myself. and neither of my parents know. there wasnt protection, but i got my period yesterday so i know im not pregnant. i still dont know what to do to get over him though? i feel like getting revenge because he hurt me so badley, but i know that wont do anything but make things worse.. i just dont know what to do?
