Bf and I have been arguing a lot!

Hi I need advice, lately my bf and I this whole summer have been constantly arguing over the dumbest things and it’s always my fault, I’ve been really stressed out bc of my job and he’s getting frustrated with how we argue so much. To the point where it would feel best to be apart for some time so I can emotionally gather myself. But I don’t believe in “breaks”. Idk what to do, is it just my stress? Or what bc I do truly love him so much it’s just sometimes I wish he’d try harder since we’ve been together for a while now.. :/
