Asking for the date is your job - so get to it. She's available, but she is also letting you know that she's not waiting around for you. Call her and ask her out.

By pre-planning the date, you'll be less nervous, and it will show how much effort you're putting out to make the date special for her, because you think she's special and worth it.
