My boyfriend dumps me after 9 months

I am 15, yes I know young, My boyfriend is 16. I was really in love with him. He was the first guy I kissed and the first time for everything else. We've got into a lot of trouble with my parents. He gets mad very easily. It's not physical but mental. One night at a ballgame, he said I was ignoring him. I wouldn't go over and sit with him. He said I was acting like I always do. He gets mad.. Cusses me out in front my friends. Here are his words>..:Don't ever talk to me,call me, talk to your friends about me, or even look at me:..< That really broke my heart..So I went over and sat with my friends. And I was telling my friends about it and they looked over there and he cussed them out.. I felt awful. I have no idea why he didn't move. 5 minutes later he left and I was having a good time with my friends. Well then he comes back.. and he doesn't say a word to me he sits on the other side of the gym. After I start to leave him and his friends are waiting at the door. and I say Bye. and he doesn't even say nothing. He says I'm his Only One, that he loves me, everything ya know? I don't know anymore. When we first started going out. I was sooo happy. Now it's like I'm walking on egg-shells.. I REALLY need some advice on what I should do.. I've put alll the things he has bought me in a box and I plan to give it to him Monday at school,is that a good idea?

well this guy seems like an as*h*le.. you shouldnt have to deal with that.. youre to young for all that drama.. and drama sucks ass... trust me I know... but just.. dont give him the time and day... just leave him out of your life.. dont even bother giving that sh*t back to him.. because that will just make him have an excuse to f**k with yer head... just throw it away... like you should do with him.. because both if em are trash
