Most Helpful Girl
Definitely text her before the date, even if it is just to confirm the date and tell her that you can't wait and reassure that you are interested. If you wait until the actual day of the date, I feel like it may end up awkward. If you have no other communication with her, what are you two going to talk about? Don't get creepy with it and text multiple texts in a row or every day. But don't pretend she doesn't exist either. If she agreed to a date, she probably is interested in you too. Maintain that interest.
