Why wont ppl answer thiss!!! What could be preventing me from getting a boyfriend?

Okay. Im in the eighth grade (Highschool next year yayyy!). And as of today, its been a year since ive had a bf. For some stupid reason, last year, when i was fat and gross and such, i had boys asking me out so often that it was pathitic (im not proud of that, just prooving a point) So ive lost fifteen pounds and i look much better now. My friends all say that im the prettiest in the cl, and i get high 1-10 ratings on here (yeah i get bored sometime) but i cant get a boyfriend to save my life. i dont know why?!?! Im less confident now than i used to be, but idk, can someone PLEASE explain all this to me, cause its really confusingggg!! Im not stuck up, and PLEASEE dont tell me that im too young, just give me your honest advice.
