About Shy girls with crushes?

Anonymous
Not really a question but feel free to chime in. A Bit of a rant based on some the answers to previous questions I posted here and my own observations :

So I've learned about a shy girl who might have a crush on me and I like her- that:
Might not look at me , matter of fact she might turn away from me and face her back to me.
If she does look at me it will be little glances that I probably won't catch.
She might stand near me with her friends at any point but NONE of them will say hello. Just kind of bump me a little and stand barely hands witdth away.
She might smile a lot and laugh with said friends just so I pick up a positive vibe but won't necessarily smile at ME.
This girl might flick her hair around and even stand there and mess it up to go with my punk/rocker type of look
wear make up
and talk in a high pitch / squeaky voice around me but still not say hi and respond to a friend's comment with a loud " wwwwhhhoooaaaa ! " to get my attention
AND
To top it off , I said hi to her once we have a brief chat only for her to never say anything since but implement a combo of the above and I am told to mend my broken heart because shy has probably gone really shy because *I* acknowledged her and I should not take this as rejection because she implements some or all of the following !

And *I* am supposed to put this all together and have it click that she has a crush on me?
Is this for real?
Am I an idiot?
How do some people even get together?
It's just me compared to them numbering 4-10 at anyone time... doom.
