@Bigshot ,
Bigshot, I will tell you the first main reason I hesitated in replying to your question, and that is because you started it with 'So'.
It is a fashionable trend go do this, I know, but each time I see it I find it distracts me and my mind starts wandering off and wondering why this trend has come about. Just a personal thing, but I find it hard to take 'so' people seriously.
Ya is not a word I am familiar with. It sounds like German for yes, or how a chinless aristocrat speaking English would say yes, but again, it makes me think twice about taking you seriously.
Then there is the question itself.
Apart from the fact that you were rude in waiting a few days before texting her after she'd given you her number, how the hell do you expect us, a group of random strangers who have neither met you nor your dreamboat, have any clue as to why she has not replied?
Your lateness in contacting her is probably the reason. You were probably doing the 'acting cool' bit, and she just thought that you were either being rude and intentionally humiliating her, or that you were playing cool, and were therefore an idiot.
She is now, when she sees your attempts at contact, probably having that song go around her head which starts "Mr Bigshot, who do you think you are?".
So, good enough answer for you? Ya?
