Well firstly welcome. Funny how you're another "randomguy" as we've had such named members in the past
I hope you get something from this forum.
Okay, sounds to me that you're a young guy, possibly still a teen even, but don't take any offense if you're not. You have written things here that have been said many times before and things that I've gone through myself as a young guy too. It's something that happens often, especially when we're still developing into adults.
You won't be able to "block" your feelings for her, so don't bother trying. What you need to do is come at the whole situation with a different perspective. Don't worry about trying to have a relationship with her, an intimate one. Just enjoy her company and accept her as a person that you can have a great friendship with, that way she will feel less pressure and more comfortable with you. Things sometimes develop from there, sometimes they don't but at least you can build a great friendship, which is incredibly valuable. I wish I didn't worry about trying to get a girlfriend so bad when I was young and concentrated more on developing myself. Build yourself into something, someone worthy, and you'll have less issues trying to attract people.
As for "making your move", take that for the dumb sounding statement it is. It sounds so predatory. She, and any woman, isn't your prey, okay? People are attracted to one another because they feel a closeness, an understanding. Beauty is just what turns your head first, but as you get to know someone, that's when you really start to feel a bond.
I would treat these as "training" relationships, where you get to know more about yourself than the other person. When you think about it, there's a reason she's not reciprocating your feelings. You still have some growing to do, some maturing, discovering who you really are, and building upon that. The same goes for anyone you might feel something for. You might very well get with this person next week and then after a while realised, "Hmm, I thought she'd be better, more accommodating, less irritating, etc etc"
So, long story short, I wouldn't worry yourself over it. If you're meant to be together, one day it will happen. You might be completely separate for years and years before that might happen. In the meantime you could meet all sorts of people that capture your attention, in different circles of life, which you should go out and enjoy.
Build yourself into the best person you can with education, life knowledge, worldly experiences, become self reliant and look after your health. Take chances and opportunities when they present themselves. A prospective partner will be enamored with someone who can look after themselves and be a rock for them. That's when you'll realise that you want the same from others too.
I can go on with more stuff, but that's probably enough to get you started.
