Letting someone win to keep the peace is smart sometimes. Doing it every time is a habit, not a strategy.

Giving way on something small to protect something larger is a real choice, and often the right one. It stops being a choice when you have done it so often that you no longer notice. Peace then is not something you are buying; it is something you are paying for continuously, at a price that keeps rising quietly.

Count the last five disagreements and ask who moved. If it was always you, pick one low-stakes thing this week and hold your position, politely and without a speech. You are not looking for a fight. You are checking whether the giving way was ever a decision.
