Are these good signs and what should I do next?

He keeps on talking to me and corrected me once. Even when I started the conversation on fb he actually talked to me. He sits next to me more often then he used to and helps me a bit. I have seen him pointing his toes occasionally. When we went to the beach he watched me boogie board and he was standing in the shallow water by himself, he might have been watching. A few days ago he asked me if I was going to bible study. He was leading it too, and he did a good job. Im pretty sure he knows I like him, I blushed a few times. We are both Scorpions and he is a year and 2 days older than me. Oh, I almost forgot sometimes he pokes me in person randomly and he always tries to admit that it wasn't him lol. I think he just wants to see me smile.
