<human>: Can you condense the text into three sentences or less?

I've been talking to this girl for maybe a month now, and one day about a week and a half ago I was sitting at dinner with her and another friend of mine at college when she mentioned that she wanted to see the new Hunger Games but didn't have a ride to the movie theater. I say "Do you want to go? I can find us a ride." and she says sure. So I find a ride, who knows I'm into this girl and decided to just drive us there and pick us up, even though I told them they could stay because it wasn't a date.

And it wasn't a date - at least, as far as we had talked. I never said the word date, she never said the word date, and me asking her to hang out the way I did in front of another person seemed pretty telling that it was just hanging out with her - despite my feelings, which I have not yet confessed to this girl.

So we get to the movie theater, and I go up and buy my ticket. I open the door and start heading in, and she follows me, without buying her ticket. I say something along the lines of "Oh I didn't think I was buying your ticket" or "I didn't buy your ticket." Not in a rude way, just one of confusion. She simply responded with "Oh" and bought her ticket. I didn't think much else of it, and it was a fun time.

But now I'm starting to think about it - did that indicate that she assumed I was buying her ticket as well, and does that mean she potentially thought it was a date? Am I reading too much into this? Did I royally fuck up?
<bot>: I asked a girl to hang out, went to see a movie, didn't buy her ticket, she seemed like she expected me to, did she think it was a date?
