By allowing you to experience and process your own distress, without my interference, I am giving you the utmost respect. I am viewing you as whole, strong, and capable. And in my affirmation of you and your inherent ability to be strong and sufficient, I am reaffirming my belief in you.
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.
