How do I know how he feels?

There’s this guy in my class who I’ve known for a while. We use to talk to each other occasionally but this year we got really close. He acts like he likes me but he can’t really show it because one of his friends has a crush on me. For example every morning when I walk into class he always starts a random conversation or does something for me to notice him. This one time we were messing around before class and he was touching me so I playfully pushed him and then he pinned me up against the cabinet and smiled. Another time we were in math class on st. Patrick’s day and I didn’t wear green so he kept touching me and pinching me. He only had a green clover sticker on so I was reaching for it and he said what are you reaching for and I said your clover. then he said well I bet if I out it down here (his area) you wont reach for it. I just smiled and he smiled back. that same day in class he asked me to feel his chest to see if I could feel it pop. Another time he got hurt playing baseball and before we could go in class he showed it to me. He also alway smiles at me, I catch him staring at me and looking at me A LOT! He also tells me a lot about his life. Our families also know each other. The most recent thing that happened was I wore dresses and skirts all last week. Tuesday I had on this short Spring/Summer dress and I had to get a book off the table I barely bent over but when I turned around to go back to my seat he had this creepy sexual smile. Then he stared at my legs all week which is weird because he usually stares at my boobs. Anyhow I just wanted to know does he like me?
