Woman advice? Maybe?

So I’m in college and im a dude. This girl is sending mixed signals all over the place. But, a small story,

Her, the girl I want to ask out, lets call her Sam. So Sam, myself and four others were eating and hanging out about 3 weeks and it came out that I have never had a girl friend, she said that was cute and patted me on the shoulder and all. So she follows me on twitter, favourites a post from a long while ago. Then in class she was sitting next to me the majority of the time, despite knowing everyone in the class very well. So, then one day she stops. Then 2 weeks late (now) she is starting to talk to me again. So today, her and I were sitting on a bus with our other friends and I ask a lady if she wants my seat on the bus instead of standing (just being a gentleman, it was obvious that I wasn’t hitting on her). Sam then tells me how that was nice, then starts telling me that “maybe this is the semester that you will find someone” and “it could be your semester”. I have no clue if she was talking about me dating her or what.

So I want to ask her to a cinema showing that is showing in our area in the UK at our school. The picture is done by our school, and it wont be open much longer. So do you think she’s interested or no? I can’t tell! Im sorry for being dumb with ladies..
