Why dont girls like me?

im 18 years old. ive been skateboarding for 9 years. every since the fourth grade ive been egtting treated by girls. for example, this one girl i liked six grade destroyed my life when i asked her out. she said, "i mean i would but then people would be like ewwww your going out with____". isnt that something. to elaborate on i am a nice guy. im black, but for some odd reason people say im a oreo. why? because i like to skateboard and listen to slipknot? is it cause im a jay-z fan and not a wayne fan? haha, lets continue. i just moved to a knew part of illinois last year. i thought it would be a good opprtunity to make new friends and meet girls. haha boy was i wrong. so far ive been rejected atleast 7 times in the last 5 months. one girl i was talking to was so into me one night. we stayed up txtin until da next day, but wen we got to school it was a different story. a couple weeks later she didnt remember who i was anymore. theres this other girl dat i liked, and im pretty sure she liked me to. she would always hold my hand and sit on me and smile a laugh in my face and all dat bs. but whenever i tried to kiss her or make it official she would say, "no, im not on dat", or "nooo stopppp." so confusing. later on i thought id have some luck when this white girl started talking to me. i thought, ok this should be fun. i mean people refer to me as said oreo so i should fit right in to her standards. i was dead wrong. when we first started talking she said she wanted to give me head and what not. currently this ***** has the nerve to tell her friend to call me and say that she wanted my weedmans number. first of all this girl has my number, and for the past like 4 weeks she will not text me back. second of all you cant chill with me and smoke? sometimes i cath her on fb and we chat for a little. but after five minutes she will say she is getting off and to text her. ofcourse, being the nice and obviously retarted guy i am, i text her every time just to not recieve a reply. i dont understand it, no girls like me. no matter how hard i try it never works. every time i manage to grow some nuts and talk to them, it never works out. is it cause im a nice guy? is it cause i skateboard and listen to odd future daily? is it cause i dont fight and dont sound black? can someone please help me before i lose control and slap someone?
