Somewhere here I saw someone Say maybe she likes that slightly awkward quietness.

I know a lot of girls who do.
I know they say confidence is attractive and it is, but we are talking about the difference between, being self assured and ego here.
Confidence IS attractive arrogance isn't.

Thing is if you ask her now and she says yes then you know for sure she likes you for you.
Well as much as anyone can be sure.x
All the best.
