Just do SOMETHING. Pick something, anything, it doesnt fucking matter. Its not like one thing will make her say yes and something else will make her say no. And if there was, she would have just been one of those dates that ditches you to hang out with her friends.
The longer you wait, the more youll second guess yourself and youll keep waiting, then someone else will ask her.
Sincerely, a college student who went through the same shit in high school and wish someone had told them this.
