Yo man that sounds like a pretty good interaction you got going there. Good thinking on your feet too!
On the subject of her flaking and not texting you back, its as Tw1sted says. Though you built initial attraction, there was no comfort built up and so in the morning she thinks of you and feels nothing. Also, adding to the fact she may have been drunk means that she may not remember you.
I think if you had the same interraction during day game you would probably have had a text back/her answering the phone, but due to the lack of comfort built up, she will not invest.

My limited knowledge on with this area is that basically you have to talk to them a bit more, find a bit more out etc.

By the sounds of it you'll have it covered before long anyway. It aint you, its her man! As Kowalski and Swype have said to me in the past "You are AWESOME." And don't forget it!
