Background: I went to the movies with this girl from one of my classes. She's been a great friend and helped me study a lot, we have a lot in common, and the "date" went pretty well. I put "date" in quotes because she asked me when I approached her in class "You know we're not dating, right?" I take a step back and see the classic dating sim menu pop up:

A. "What, do you have a boyfriend or something?"
B. "What do you mean? Wasn't that a date?"
C. "Uhh, yeah, sure..."
D. Put it in

Being the obviously quick-witted man I am, I punted and chose C. The real question is now, should I keep trying with her or give up? Moreover, how should I approach what she's said?
