How do I get guys to like me?

ok so im very nearly 16 years old.. and i just now had my first boyfriend. but.. it only lasted a week. he and i have known each other since like 2nd grade, but there was always the "ewww boys have cooties" problem up until a couple years ago. then we were good friends. he was probably my best guy friend.. then he transferred schools and i didnt see him forever. and in the meantime, i grew up and started having interests in guys.. i mean, what teenage girl doesnt want a boyfriend? but the only people i EVER attract are older men! honestly.. at local rodeos and parades and any time i'm out with my friends. all the hot young guys hit on my friends and all the old ones hit on me! i dont get it... im not ugly, im not a *****(most of the time haha).. so idk. i've felt like there was something wrong with me forever. then.. about a month ago, i saw my old friend. and i got butterflies and started blushing. :) it was so.. just out of place. but i embraced it. i started flirting with him and texting him.. he flirted back and said all the typical cute things :). we started hanging out and he knew i liked him a lot. and then he asked me out :) first time EVER any normal guy my age had shown interest even a little in me. i was soooo happy. he was also my first kiss :) and it was great and he seemed like he was really into me, but then a while later he broke up with me :( over text too. and when i asked him what i did wrong he said that i didnt do anything wrong and that im a great person and an amazing girl and not to think i did anything wrong. so i asked him why, and his response: "i just can't see us being anything more than friends"... OUCH. why couldnt he have figured that out before???? so now im back to feeling stupid and like no one is ever gonna want me.. im not looking for a bunch of sympathy. im just asking what do i do? preferably from teenage guys.. no younger than 15. im not bad looking so ive been told, im a dancer so im pretty in shape, im a generally nice person, im very open-minded and positive.. idk what else to do. help me please!!!
