Are these signs that my crush likes me?

He asked me to dance at a dance Kept smiling at me during the 4 dances Told me my hair smelt good Haven't talked to him really so idk why he asked me to dance :) Looks at me from across the table/room Didn't sit beside me like he was supposed to but looked at me across the room Says I can't help but flirt with you Kept pushing my chair away and closer towards him Sang to me while we danced;) And I am confused by these: He got a gf about a week ago during summer but I don't think he knows I like him Seems shy around me He doesn't really get a gf a lot
