i just can’t take it rn

my bf and i are about to hit 3 years and the past two or three months have been a literal hell of arguing. like i would say 80% of the arguments are about things on the more serious side, the other 20% being small things that turn into big arguments but i’m loosing my mind. we always argue about the same rotation of things which makes me so frustrated and argue even more about the fact that we have to keep having the same conversations. i just want us to be at peace. he keeps saying i’m “so easy to upset” but i’m like yeah wtf you’d be pissed off just as easy to if i were to act like we didn’t just have a conversation about this a few days ago, showing how everything you said was in one ear out the other and not important enough to remember!? throughout our three years, for the majority of the time we have our normal relationship little bickers here and there but then randomly for a month or two we go through a phase that feels like arguments every other day and it’s just so overwhelming. i feel like this is probably the second or third time we’ve gone through this kind of phase and it always seems to happen in the months leading up to our anniversary. i just needed to rant because we just had another argument and i wanted to pull my hair out because it was about something we had a lengthy conversation about TWO DAYS GO to which he stated many times he understood what i was saying. dear lord help me. our relationship is so great aside from whatever the hell this anniversary curse of arguing is
