What do i do now? it hurts soo much=(?

It hurts so much right now. i don't know what i can do about it tho. I took a chance, and I asked the guy i like to sadies, and i said it just as friends so it wouldn't weird anything out. i asked him and all, but he said he was happy i asked him but he just doesn't do school dances. so no. at first it didn't bother me much because i was happy that i sucessfuly asked him, but then it came. the feeling as if i had been stabbed in the heart. i really love him. i do. and now how do i get over it? What do i do? Why does it have to hurt so much?
