Helpp😭

So my boyfriend and I have been having a lot of problems.. which I mean he gets mad at me for a lot of things but I assume a lot of shit but I’m trying to change. He’s stubborn. He just told me he wanted a break but I don’t want too because I don’t want him messing around with other girls and I care so much for him that I want to work it out instead. I just don’t know what to do. Any help to make him not wanna take a break with me? I have already convinced him one time not to do it.
