Sometimes you lose someone because you finally stopped losing yourself.

Sometimes a relationship only worked while you were willing to overlook, absorb, or shrink, and when you stop, it cannot hold the new arrangement. The loss is real and it can feel like a punishment for finally taking care of yourself. It is worth being clear that you did not cause it by getting healthier. The relationship simply depended on something you were no longer able to keep providing.

If someone has moved away after you set a limit, let yourself grieve it properly rather than reasoning yourself out of the sadness. Then notice what you kept. Some losses are the price of a change that was necessary, and they still hurt.
