How could I cope with this?

Okay me && my boyfriend just broke up about two or three days ago && now just recently hooked back up he broke up with me over some stupid ish..4 callinq my best friend bookie and babe okay he thinks we were talking inappropriate and we were really talking about the beach on my a social site page soo he gets mad & starts calling me grimy and stuff so I’m like you can’t be getting mad not only I saw him calling this other girl baby && feeling on my friends and taking pictures with other girls bhudd when I talk to my male friends he obviously guesses we talking about sex & I’m trying to tell him if I ain’t let him do it yet why would I let another dude… and my bestie lives all the way in Minnesota not only talks to other girls he tells my business to my friends about how I unblocked this dude because he was talking junk okay the boy does like me but he has a girlfriend since unblocked him he hasn’t said a word to me about anything bhudd he is telling my friends everything I dont tell them everything because they not in a committed relationship with me so they are just my friends and not yet do I go around asking people because he has smoked & he actually agreed not to it was a party for my older sister my cousins came & he went outside & my older brother & my other cousin so me & my friends were dancing he come back smelling like a black and he said he sorry when I was at the steps soo we go back dancing he goes right back and do it again and he acts like im a bad guy yess I am 13 years old and yess he is 17 not trying to be mean he acts immature and if I told him he would get upset he argues with my little 8 year old brother and when I have other stuff to do he wants to be around me 24/7 im like CAN A BITCH BREATHE I DONT KNOW WHY HE GETS MAD WHEN I TELL HIM TO STOP…so ever since we went out I want to know which one in this relationships has more faults?
