I want to break up with him but idk?!

We fight way too much and we’re really young I’m 18 and he’s 21 and last time it got bad to the point where we broke up because he said he no longer loves me out of anger and he said he had his reasons because whenever we argue I try to leave him and he said he just wasn’t feeling the love from me anymore and told me he straight up doesn’t love me and he still doesn’t know why he said that but I know he does and he knows I love him but we just fight too much and I’m just questioning if this is even worth it anymore? He got mad at me because tomorrow we were supposed to go to his little sisters graduation and he kept on telling me different times I was supposed to meet him and I got confused and he was busy cleaning his house all day for me and I just told him to call and he blew up at me? He called me inconsiderate when I’m going out of my way to meet him 25 minutes from my place to his and borrow my dads credit car so we can pay for uber and I could pay for our graduation dinner??
