Soo What do I do about thiss guyy?

okk so theres this guy i really like. and i used to have him first semester 2nd period. and we would talkk and stuff. then i had him 2nd semester also same period. we still talked and yaa. then i got switched out of the cl. and well i see him around school, we hug and sayy "heyy." and thats it. but i thought something between us was going to happen. i could feel likke at any moment he was gonna askk me out. but he never did. idkk i still feel like theres something between us. but heres the problem: i see him talkk to a LOT of other girls. but hes not a player. soo i know somethings probably not gonna happen between us. soo how can i make him regret forgetting me? or something to tryy to talk to me again? thankk you. god bless.
