I can’t stop fighting with my boyfriend

Me (20F) and my boyfriend (21M) have been dating for almost a year now (11 months). It’s been pretty smooth sailing but the fights are becoming more frequent and I don’t know what to do. You see, i’m not the most reasonable person when it comes to arguing with… anyone basically. I have a very hard time with knowing when it’s time to just stop and step back, I get very angry very quick, I often bring up things that aren’t even remotely related to the issue at hand, and i‘m VERY self destructive. Me and my boyfriend used to have normal fights, but recently they’ve been absolutely horrible and have lasted hours and hours with very hurtful things being said and little to no resolution.

We as a couple have not tried many things together to prevent this but individually we have tried things to prevent it. I’ve tried to step back from things when they’re escalating, but I often wait too long to step back and by the time I think about doing it my negative emotions have convinced me that the fight is necessary and it getting somewhere. I’ve tried taking breaks from arguing to calm down but it only continues once i come back to the argument or just to talking in general. He’s tried similar stuff but clearly neither of us are doing anything that is helpful. I’d like to also point out that i believe that he doesn’t need to do as much as me to prevent it because i truly believe i am the problem here. I don’t know if i could be wrong or not but i have acted the same in past relationships.

As of right now, we’re planning to take a break from eachother to see if it’ll help, but im very worried that it will just return to the same way it was before. I don’t want to leave him, and neither does he but i don’t know what i should do. Should we break up? Should we look into couples therapy? Is there another method I could try? Please help.

tl;dr me and my boyfriend are fighting very intensely and frequently, and nothing seems to help.
