I need help! I've got a huge crush!?

wow. well i think you should stay in touch with her on facebook, then text her sometimes. maybe about and inside joke or something. and keep getting to know her that way. then you can ask her out and it wont be that awkward bc youve been keeping in touch, and if she says yea, yay for you. if she says no, it means she doesnt like you and you should move on. but stay friends on facebook
