A relationship should add to who you are, not replace it.

Closeness should widen the world rather than shrink it. The warning sign is quiet: friends who stop being seen, a hobby that goes untouched, opinions you now check before saying out loud. It happens by small trades, each of which seemed reasonable at the time, until one day the list of things that are only yours is very short.

List what you have dropped in the last few months and pick one to restart this week. A friend you stopped texting, a thing you used to do on Saturdays. Someone who is good for you will be glad about it, and that reaction is useful information either way.
