How do you know if a guy like you? PLEASE ANSWER!!?

i go to an all girls school and every saturday and i go to tuition for three hours i have been going for 2 months now and this guy i like smiles at me when we are doing our work and ignores me when he is with his Friends, i am the only girl there, so i do get a bit annoyed, also he isn't afraid to tell me to pick up his pen and he says my name sometimes, outside school he saw me in my cousins garden and thought it was my house and said hi, he asked my cousin about me once and today when i saw him alone with one of his Friends he gave me a faint smile and kinda moved his head, and looked in my eyes. he is so cute, and i don't know why, but my first instinct is to ignore him, is he feeling that way or does he just not care? one time he teased this weirdo boy likes me and i made a face, he smiled faintly. so does he like me?
