When your phone updates, some old apps stop working. When you update, some old habits and friendships will too.

Some connections were built around a version of you that no longer runs, and when you change, a few of them stop working without anybody behaving badly. That is a quiet loss and it deserves to be felt rather than explained away as necessary pruning. It is not a fault in you or in them.

Let the ones that are fading fade slowly rather than ending them formally. Some will come back in a different shape. Put your attention into the ones that still fit, and be gentle about the rest.
