The trick in keeping your relationship vibrant and healthy, is to micro correct towards each other, towards the join between you. By showing your partner you are willing to own and handle the little issues that come up during the course of a week, you are giving them assurances that you can do the same over the longer trajectory of your relationship.
You must give your partner the assurance that you are not running away. And you must also allow them to hold their own pain. By "staying in your own lane" you are giving them several strong messages.
