I like a girl she is hot what should I do?

Hey! If you like her that much that you want to be her boyfriend ... just ask her to go out! If she say "no" she just isn't for you .. i mean i'm sure that you are a good, cool boy and she is gonna miss her chance with you! xo-Bella

Well first you could glance at her a couple times in class.
And if she's talking to you alway's give eyecontact to make her feel like your interested in her storie or joke even if you arn't. And maybe after a few week's you couod ask her out.
But if that dosn't work then SORRY
