How do i get my bestfriend to kiss or ask me out?

need some advice. I have a guy best friend and we're very close. We have a lot in common,we have the same birthday and everything but I've come to find that I have fallen in love with him. He's a year older so more mature. He's always has held my hand, given me hugs, etc but I never followed up with it. I used to think it was gross and I used to push him away and I feel like an idiot. Ever since the summer we've gotten closer then ever even though he goes to a different school now for freshman year(high-school). We talk on the phone for awhile, webcam, etc and I still didn't follow his lead. I used to be afraid that people would think we're together. We always went to the mall together and he'd always pull me close to him and slowly It started not to feel weird. It all changed last month when a friend of ours had a quince. It was like a night of romance. We dance, locked fingers, he held me, and I liked it. It was like we were dating. I remember at the quince we danced to first dance by nevershoutnever and we were the only ones on the dance floor. Someone asked if we were together and he said no, then the dj said we'd make a really cute couple. So he pulled me by my hip to his and said "Really?" and smiled at me. My heart has never beat so fast. Unfortunately after that night he didn't pick up where we left off. Is he trying to get out of the friend-zone that I've kept him in for so long? He always calls me adorable, his one and only best friend and I'm getting really confused. I get really jealous if other girls talk to him lately. And there's times that when we're walking or talking he's staring at my not my face. Sometimes I'll think "He must like me" and sometimes I think "There's no way he could like me". Maybe he doesn't like but he's attracted to me. He's out of town for Christmas he texted me that he missed me. I'm afraid that I might let my insecurities push him away. I just really want him but I don't want to smother him. I'm not afraid to call him first or anything but I don't want to annoy him. I just want him to kiss me thats what I really want right now.
