Should I break up with my boyfriend

I ‘15/F’ and my boyfriend ‘16/M’ have been off and on for 2-3 years. The first time we broke up it was my fault and I broke it off. We got back together at the start of the new school year. The second time we broke up we were having a bunch of problems and I wanted it to break up. After seeing him break down, him leaving school early, and an hour+ call with him after school, he convinced me to just take a break and we’d get back together at the start of the next school year. Well, we did that and we have 1-2 problems each week. I’m not happy anymore but finals are also right around the corner and I’m not sure whether it’s stress or how I actually feel. We had a big fight over a small thing I said and my bf said “I was so mad, I was actually thinking about breaking up with you”. I’m not sure what to do, but I actually thought that he should. What should I do?
