Ah adolescent bliss. Sorry for being the pessimist here but I highly doubt you're in love. It sounds more likely like your first crush. Now, I'm not saying that you could never love this girl and by all means, you two could end up loving each other very much and having a great life together, but you're not in love yet. First love...well, to put it one way, you never know you have it for real until it's too late. But hey, don't let that stop you from asking her out. You portraying that you two get along well, you share a sense of humour with eachother, which is imperative and you've clearly got the hots for her. You have to consider, though, would you really want her as a girlfriend and have the risk of losing or tarnishing a great friendship as a result. It may happen, it may not. If you really really want this girl, you take that risk, you have no regrets and you support your decisions and will to the end. Yes, there may be consequences, heartache and risks, but remember, if none of us had the courage, we'd all be extinct by now. Ah love..."'Tis foolishness! If all were so easy, why none would suffer in this world."
