What are the signs of a guy liking me?

I have liked this guy since the seventh grade . Now im in the eighth. All of a sudden he just started to notice me and has been looking at me alot. bởi alot i mean one of my guy Những người bạn caught him and he just keep staring at me. I really like him. For example... last friday there was a Halloween dance. I went I told my Những người bạn ngày that i wanted to dance with the guy i like, her ngày went over and told him. As soon as i saw them looking for me. I freaked out got my friend and ran away. Yesterday in english and đàn ghi ta, guitar he keeped looking at me. Also he doesnt know how to read notes and all of a sudden offered to play melody with us once he saw mr with the others who will be playing with me. I really like him but im really shy but hes a được ưa chuộng kid im not so được ưa chuộng I know alot of people and they know me. But he know way more. Another problem girls are all over him !!!!!!! What do I do????
