How about, instead of being a vagina and havig everyone make the move for you, you break out of your shell and learn like everyone else? You're going to get hurt, but you'll come out of it stronger.
Anyway, actual advice;
If she has a crush on you, you're in. forget that other kid, she said she was into you, not him. If you're actually interested, make a move before she thinks you're a spineless pusillanimous individual.
