Im somewhat confused.. pls help!?

You asking her didn't go the way you planned, but HEY, she said yes. Don't over think stuff, it'll drive you crazy. I think sometime during the whole prom thing you should tell her you've been friends a long time and you really like her and you MEAN like her. She's probably in agony thinking you just want to be friends with her. Trust me (because I know I'm older than you) in life it's always best to SAY WHAT YOU MEAN. It will be a great relief to you to know one way or the other, won't it?
