Dude,
There are various ways which a gal can drop hints to you when she is interested in you but the thing is whether you, yourself catches the hint/s.
But then again, if the gal already know that you like her and doesnt show any actions. It can be positive or negative.
Positive Situation:
She may be too shy to show any hints and is waiting for you to make a more 'visible' move.
Negative Situation:
She want to reject you but don't know how to get her words out of her mouth thus, she chosed to remain slient.
But then again, it is good that she doesn't shun you.
Good Luck dude...
