Could he like me or am I overthinking it?

So I went to the movies the other night with a group of friends. The guy I like was there too. We saw the new pirates movie and i sat next to him but nothing really happened there. After the movie a couple of us watched another movie at his house(it was like 2am) I sat on a couch with him. I had a pillow on my lap so he like, layed on me, not on my lap but like, on my chest(not boobs haha). I told him I didn't know what to do with my arm so he put it around him an we were like that through the whole movie. Idk if he did that because it was comfy or if he might like me or what. What do you think he intended by that? I might just be overthinking it but :P
