His hands were shaking when he was with me?

I was with a guy that I'm seeing and we haven't seen each other in a while which is unusual, we have only talked. I was really nervous to see him. When I did meet him I noticed how his hands were shaking! He was holding an object in front of me and it was shaking. I like him a lot so is this a sure sign besides everything else that he likes me?
