Ok, first of all, she didn't say no. Don't twist words as you desire mate. Though, fill me up with more details and I might help you with some useful advices. I don't understand what you mean by:
I've been hitting on this one girl for a while now, always liked her.
Be more precise. What did you actually do? Because you know, acting like "just another" may put you in that "them" category. It matters
so damn much how you speak with the girl, how you behave when you’re with her. Be different than the others, let time flow, don't push things. There's always "tomorrow". Talk nice to her, impress her, blow her mind and she can come under your spell. Even so, all girls are different, but if you’d watch carefully you’ll see that they’re all the same at one point ‘eh.

Also, don’t show her you’re mad about her, mehh, that will just make her distant towards you, slowly but sure. More? Don’t know, waiting for your details...
