Help with my ex boyfriend! i know its long, but please help!?

i'm in the 8th grade now and um ok so i have this ex (chad) and he's one of the funniest people i know and EVERYONE says we could be brother and sister cause we're so much alike to a point that i get annoyed from hearing that all the time. well, i broke up with my bf of 6 months and shortly after that breakup, i started dating chad. so, he is a notorious druggie and only smokes weed but he did a lot and he'd had sex before. i haven't. chad and i were good friends for about three years. i told him i liked him and we started dating so he stopped smoking pot for me and was probably the best boyfriend i ever had. he made me so happy, he was SO sweet to me and said he loved me. he had never ever said that to a girl. then, BOOM! something happened. he dumped me out of the blue. he wouldnt tell me why, but one of his friends said it was probably cause he was bored, but not to take it offensively cause that's just what he's like. i was so upset. we're still good friends now, and i have another bf, but i cant get my mind off of chad. im about to start smoking pot surprisingly. im gonna be honest and say i am one of the top 5 most popular girls in the grade and my new bf is kind of a goodie two shoes. ive been farther with a guy than he has with a girl which makes things awk for me. chad still texts me things occasionally saying "you looked really pretty today" and stuff like that. i just don't know what to do. i really really like my new boyfriend, don't get me wrong, but i think i might still love chad. IM the one with all the boy advice in my "group" so my friends cant help me....how do i win the way to this pothead's heart? should i tell him im gonna start smoking cause then he might want my first time to be with him... haha:) please help me!
