What do you think about this body language from a Canadian woman?

I met her in my French cles; she used to come with eye gles but all of a sudden she stopped wearing them and she has started coming very pretty. She ended up sitting next to me in the last cl and the instructor put us together to do an exercise. She was all the time tossing her hair and twirling or flicking her hair exposing her neck in some cases. During the break, I was with a group of people from the cl and she was alone but then she joined to the group and ended up next to me, I made a comment about the conversation and she laughed. Then we ended up talking just between she and me and I (we) starting making the first open (personal) questions such as why she was studying French, etc., she also asked me the same question and I responded that I was working for a French company and she immediately asked me "what do you do?", we continued talking 'till the end of the break and returned to the cl. She had to leave early and we will not see each other in 2 weeks.
