I agree with others, it sounds like she really likes you, possibly as more than a friend.

I know these things are hard when you are shy, but I don't believe you've blown it, she's still on the scene after all and giving every indication she likes you.

Best of luck to you.

PS - As regards your shyness, she may well find that attractive, lots of women do, so just be yourself that's the best you can be.
