i need help

i'm 14 and my bf is 16 and i love him but sometimes all i want is to break up w/ him because he is so stubborn and he doesn't listen to me...idk what i feel anymore, i know i'm too young and things but he is the only one who listen to my problems and try to help me when i have problems with my parents or school...and now he drank too much and i hate when he drink alcohol cause he is feeling sick after and i hate to see him like this but he doesn't understand that...idk what to do...should i break up with him?

btw sorry for my english, it isn't my native language...i hope you'll understand what i wanted to say
