Does he like me? Plz help!!?

OK. So I have this friend and I've had a crush on him for years. He used to hate me last year but now, he's friends with me. We got lockers right next to each other and we like to push each other away from our lockers and poke each other with pens and stuff like that.. My other friend had the other locker right next to me and it was right before the dance and she asked him, Sooooo you still taking Melanie to the dance??? He said IDK.I was mad. It was before she knew I liked him, but that day I told her I liked him and she flipped. So,then we ped notes about him(dont ask what it said) and then everyone knew I liked him. So at the end of that day, I'm getting my stuff out of my locker and his friend Chris, he knows too, came over to him and told him. He looked at me and his face was white. I slammed my locker and just walked away. But, we're still friends, I mean we have our arguments but we eventually make up. What could it b???
