<human>: So last period in school I had a schoolproject about making a small movie with these two girls. We really enjoyed doing it, and had fun doing it. Before the project we knew each other, but didnt really ever talk or anything. 

As the end of period drew closer I really started liking their company, espacially the other girl (they are each others best friends). We started saying helloes and talking a bit outside the project, and I started crushing (is that a word?) on her. 

I am really bad in reading women (also never been in real relationship before thought I have many girls as friends), but I think she might like me a bit too, or at least not hate me. If we meet somewhere she always smiles and says hello, sometimes wants so talk a bit more as well. 

Our school also has this thing that you can buy a small candy and a card to be delivered to someone on last day before break, and I got one signed by both of these girls I was in the project. After I got it my crush came to me and asked if I got it, I answered yes and thanked her (and later on the other girl) alot. 

So my question is what should I do now? Is she really into me and should I try to go on, or is this just natural kindness from girls? 
Our project is on break until somewhere after March, and I think that is too late to wait for.

 The another thing that makes this kind hard is that she might already have a boyfriend of some sort if my another friend is right. I dont feel right to try to "steal" a reserved girl. On the other hand I know that teenager relationships tend to be fragile as is..

I am thinking about asking him how her xmas went after 24th day on Facebook, but I dont want to us to lose our friendship in regards of trying to be even more. I also dont want to harass her with unneeded messeages if she doesn't like them. Do girls generally like if they get sent a msg?

Oh damn, that was a long.

Can you condense the text into a few key points?
<bot>: Have crush on girl (who might already have boyfriend) from my schoolproject, am I right thinking she might like me and should I keep on messeaging her or something?
