What I would do is ask her out. Take her on a few dates. Like walks, movies, and possibly lunch or dinner. Doesn't need to be expensive though because you're young still. You can go out shopping as a date too. Find out about each other. Well, for me personally I would find it a bit creepy. Usually I would like to have a parent there so nothing unexpected happens. You can ask her, but talk a few times. See what you have in common. What I get told is even touching someone's hand you can feel chemistry. Just be yourself when you meet her, that's all I have to say.

Stop getting to know each other over Snapchat!!
She wants you to be a man.
Tell her you're taking her out.. Set a date.. fix a time and pick her up/meet her and just have fun.
Go skating together! There's enough places this time of year.. And it's a fantastic way to see if you're comfortable in each others space without staring awkwardly across a table at each other..
