CAN'T TAKE IT ANYMORE HELP ME PLZ!!!

I WANT TO LEAVE MY BOYFRIEND, BUT I DON'T KNOW HOW TO GO ABOUT DOING IT? B'CAUSE HE HE HASN'T DONE ANYTHING.

my reason for this is
i think i'm too young for commitments and dedications
and i just don't want to be in it anymore.
i just want to b free,and have some fun with myself and friends.
i'm not leaving him foranother guy ,i know that's exactly what he'll think.
i'm just 16 and now i think my mind should be focused on my sch. work and more constuctive things than bf's.
no.1 i hardly have time 4 him cause i get so much hw during the weeks and weekends i don't have time for him, so i don't think it makes any sense at all.

HELP ME PLZ
THANX
