Strategy is noticing patterns. If the same fight happens every Sunday, the problem isn’t the fight.

Repeating arguments are rarely about their stated subject. A row that lands at the same time every week is attached to something structural: the schedule, the money, the thing nobody says, the tiredness that always arrives on that particular evening. Winning the individual argument changes nothing, because the cause is still sitting there afterwards. The pattern is the real information.

Write down when the fight happens rather than what it is about. Look for the common factor: the day, the hour, who was there, what had just finished. Then change the circumstance for two weeks instead of arguing again.
