I think he likes me? what's your opinion?

I absolutely hate asking questions like this but anyways. I was camping with a club and I was talking to (lets call him Dave) an we were pointing out the few constellations we could see. some of the younger kids were annoying me so I said that I was going out to the field to look at the stars. so I was walking out there and I noticed dave was following me. when we got to the field he said do you know where Taurus is? and I said no. so he put his arm around me and showed me the constellation then we were talking still in the field and he said I think the whole no dating in the Club thing is stupid. I said me too. we were the only people in the field. and we laid thereand talked for about 2 hours. he is always glancing at me and when we played the human knot game thing he made sure he was holding my hand. so what do you think. does he like me?
