HELP ME PLEASE!!!!!!!!!!!!!!!?

ok so one night, me and my friends decided to prank call one guy in our grade. he found out it was us. so then we called back and talked for hours (we pulled an all nighter!) then i said to my friend, i really like this guy and they heard and he said what? what victoria? and i was like umm nothing..... and my friend alexis blurted SHE LIKES U!!!! and i was like shut uppp and then nick (the guy we were talking to) said u really like me? and i was like yeahh and he said i kinda like u to. so a long story short, he asked me out and i said yes. i broke up with him the next day because i felt like i was cheating on this boy i liked even more in a different town. so its been a week, and now my friend alexis is going out with nick and nick is my best friend. but now i have a crush on him again. i want to go out with him again, but since I broke up with him, i dont know if he will ever want to. what should i do?
