Now it’s starting to feel more like MY life: this is how things will be for me from now on.
And, that is really how it (detachment) seems to happen in my experience. You just keep at it and suddenly notice you're more in control of your feelings and how you experience them. You feel good about taking care of yourself again and reaping the benefits of that care. Our partners aren't the driving force behind it. We realize what is truly best for ourselves and that it is OK (if not mandatory) that we give our mind, body, and spirit the care they require.
We forget about how enjoyable moments like watching a friend DJ can be. Put away all the work and home "to do" lists, compartmentalize the M for a bit, and be in the moment. Hope the rest of your weekend went as well.
