Does this girl like me?

Ok well i really like this girl and we have been friends for 2 years now and im 15 and shes 16 anyways during a movie(not scary) she had her hands all over me and her head was on my shoulder during pretty much the whole movie, i didn't really know how to respond so i kind of just sat there and kept watching the movie btw we werent alone there were 2 more people watching the movie with us. She also puts her head on my shoulder at other teams were together. Also when we were watching Scream 4 it was me and her and 2 of our friends and she decided to sit next to me and she held my hand the entire movie and her hands were sweaty if that means anything. Lastly she knows i used to like were a little big ago and she asked me when i stopped liking her and i said idk a long time ago and she said stop leing. What do you guys think, oh and im shy and i don't really wanna ask her out because i don't want to get rejected but are there any tips on if she puts her head on my shoulder again and i wouldn't really want to put my arm around her because if im scared to make her feel uncomfortable.
