I like a guy. is he interested in me or just playing ?

we are classmates. i never told him that i like him but i think he knows bc he smirks when i look at him. and today he saved seat for that girl where i was about to sit. and saying it loud so i can hear that he saved seat for them. he is being extra nice to all other girls except me. he was sitting with a girl and kept looking back at me to see my reaction. i did'nt react and did'nt even look in his direction then he became sad.

also when i was sitting behind him i laughed at his friend's (guy) joke and he tried to shift attention to himself. he is weird. how can i deal with it? what does he really want?
