The most loving form of detachment I have found has been forgiveness. ~ Family Groups, Al-Anon. Courage to Change—One Day at a Time in Al‑Anon II

Emotional detachment can be a positive behavior
which allows a person to react calmly
to highly emotional circumstances or individuals.
Does someone in your life seem to control your thoughts,
your decisions, your actions? It can be someone past or present.
Does someone’s voice in your head control your self-understanding,
your self-concept? Look at it, find the resentment, and forgive
your someone. They never made you feel like you have.
They may have wronged you, but the emotions,
the reactions were yours. And you can break the ties that bind
by understanding, by accepting, by forgiving…and the binding
drops by the wayside, leaving you to find self-acceptance
in your life.
