I'll be honest here and this is speaking from experience.
It is clear that you like her and she appears to like you. It is clear that both of you been over nurtured by your parents too much (same as most kids this generation it would seem) as these responses seriously match what a 10 year old would do.
Now moving on to the actual advice. I was never this immature at your age but I was in the "friend zone" as you. You mentioned you are friends, well that is all good. However clearly there is more there than that but both of you don't want to admit it. Well I had a friend of the female species like that for a good 5 years. We both like each other but we never talked about it to become a couple because all we thought about was lets finish school, play games and plenty of time blah blah blah.
Next thing, she moves away suddenly with her parents (she was 20) because her brother had a sporting opportunity. She was crushed as she didn't want move, Over time we slowly stopped talking as much to each other as back then it was expensive dialup and expensive long distance calls. A year later she had a boyfriend and the rest is history. We still chat every now and then and even talked about it once. When we see each other in person it is always "what if" look that we give each other and smile and pause for a second staring.
Now if we were totally open and honest to each other she probably could have stayed and we could have moved in together and provide that comfort that we had from our parents at the time. But I was younger than her at the time and figured there was some time for me to get my shit together. Who knows were we would be today.
The moral of the story is work out quickly what you both want before you regret it. Don't rely on your age to give you time to sort it out later.
