Same fight, different props. What makes it repeat is usually somewhere underneath the content.

Couples who have been together a while often have one. Sometimes two. The argument that arrives wearing different clothes: the dishes, the in-laws, the money, whose turn it was. You could both perform the other's part. You know the beats. And you have the strong sense of having had this exact conversation before, because you have, perhaps four hundred times.
The reason it never resolves is that it is not really about the dishes. Solving the dishes does not retire the argument. Something else shows up wearing the next costume. Underneath, most repeating arguments are one of a small number of questions being asked over and over without ever being said out loud. Do I matter to you as much as you matter to me. Am I alone in this. Do you see how much I am carrying. Am I going to be criticised for this too. The dishes are simply the available vehicle.

There is a shape most of these take, and it is worth learning to see while it is happening rather than three days later. One person raises something. The other hears criticism, which may or may not have been intended, and defends. That defence lands as not being taken seriously, so the first person escalates in order to be taken seriously. Now genuinely under attack, the second withdraws or escalates back. Each move makes complete sense as a response to the previous one. Both people are behaving reasonably, moment to moment, and the whole thing is a disaster. That is why it repeats: nobody is doing anything obviously wrong.
Not better arguing. Not a rule about not going to bed angry. The thing that interrupts it is one person, mid-loop, saying what is actually going on for them instead of the next move. Which is much harder than it sounds, because the actual thing is usually more exposing than the argument. *I feel like I am doing this on my own* is a considerably more frightening sentence than *you never do the dishes*. That is precisely why the dishes get used.
That is common and it is not automatically a verdict on the relationship. Some people find this kind of conversation genuinely difficult rather than uninteresting. Others grew up in houses where feelings were not discussed and have no practice at it. And for some, the fear is that starting means a long unpleasant process with an uncertain end. You cannot make someone willing. What you can sometimes do is change your own move in the loop and see what happens to the shape of it, which is one of the things individual work is useful for even when only one person comes.
When you can both see the loop and neither of you can get out of it. When the arguments start leaving marks that last past the argument. Or when whole subjects are being avoided to keep the peace, and the list of subjects is growing. That last one is the quiet signal, and it is usually further along than people think.
