It's hard to say for sure, but my impression is that you haven't. Like Caberg said, she must be dealing with some issue, or otherwise she changed her mind about you. Who can say what?
You have two options here: either you keep waiting for her or, in a very polite way, you ask her out again. See what happens.
If she is "rude" with you or ignores you again, then you better leave her alone.
