Relationship help for teenager?

i posted a question few months back saying about me and my boyfriend were having a bit of trouble, i told him straight out how i felt but i don't think he understood what i was telling him, him and his friends were planning this trip aboard and i told him i didn't like the idea cos the last time he went out and got drunk he cheated on me with a guy! he didn't like that i was controlling him? so he dumped me, now he wont even talk to me he has caused our mates to be pissy with both of us and one of them to cry cos of the arguments, what can i do to sort this out i still love him and want to talk to him but he is not having any of it he doesn't really care he made his friend cry the other day. i don't care if we get back together i just want to be friends with him again i really miss him, please any help and advice useful
