need advice

Chloe
So I'm currently 15 and so is my boyfriend, we've been dating for over a year now and have gone through quite a few ups and downs until yesterday when I decided I'd had enough, it had gotten to the point where I had given him lots of chances already and it had become an abusive relationship, tbh I didn't really think it was a thing unless he put his hands on me so I brushed it off and told myself it would get better but it never did, it actually got worse....so I told him after he had said a few hurtful things, that I basically had, had enough and I didn't want to be in an abusive relationship anymore...... he has since been texting me nonstop and is trying to get help for his anger issues, and keeps asking for another chance, he keeps saying that he will change and it will get better............I honestly have no idea what to do, please help
P.s I know this is really long thankyou to anyone that reads this
