Search Results: movies or restaurant

I've known this woman for over a year now. We met through a mutual friend & that friend asked me to help her improve her English. We would meet once a week for an hour & occasionally with our group of our friends.
This year things have changed. Without discussion she has been wanting to spend 3hrs+ together every time & sometimes we aren't really doing any work, just spending time together. Also, while she is a friendly-touchy person, things have increased. She has also given me a pet name!

Apart from the English lessons, we rarely did anything alone until recently.
* Last November she asked me to a movie & paid for the tickets. I assumed others would be there with us but when I got there I found out it was just us. This was odd for us to do.
* April when I mentioned going to an event and she jumped at us doing it alone. We also went to a restaurant for dinner before the event.
* Then a week later we took a day trip to another city, having dinner in a restaurant again.
* 2 weeks later I had planned an event for some friends. She asked me to meet her at 1pm and we would meet the others at the event at 4pm and after the event (6pm) all our friends were going to have a BBQ. Between the event and BBQ I took a bus but she walked with another male friend (who I thought she had a crush on). At the BBQ she was unusually quiet with me. When we next met she told me I had abandoned her, that we were meant to spend the whole day together, that she wanted to be walking/talking with me and not that other guy. She was quiet at the BBQ as she was upset with me. It was 1hr apart! This screams to me as irrational for just a friend.
* Today, via text, she asked me to the movies again. Either Fri or Sat night this week (day is my decision as it depends on what day I must go to her city for my work).

There are other things too.
I guess that our mutual friend has told her Im attracted to her by now.
Im just curious if these are some good signs or just friendship. What do you think?
