I need more answerers please!!!?

my crush is always calling my name. He talks to me the most. We always look at each other in the eyes. When we sit together our legs touch. He's always teasing me. When we talk he gets a little closer to me. (i really like him!). Sometimes i think he just pes my way on purpose like if he has to sharpen his pencil. And sometimes you wont believe how close he is to my face! Is he showing signs and if he is how can i show signs back?
