Mmmmkkkkkaaaaayyyyy :)?

ok so i've been dating this guy for the past like week and today he was coming to my basketball game after school. So i walked around with him for a bit after school before my game and we were standin in this corner kinda out of sight and we were just kinda huggin and stuff and i told him i had to leave and he was about to kiss me but i just left. I feel really bad now but hes the first guy i've ever been nervous with, do any of yall have any ideas on how i can make him forget that i completely rejected him yesterday?
