If you’re always the one driving to them, notice who never learned your address.

Effort is easy to hide when only one person is making it. You do the driving, the planning, the checking in, and because the friendship keeps happening it looks mutual from the inside. Then you stop for a month and discover it was mostly you holding it up, which is worth knowing and still stings.

Go quiet for a couple of weeks and see what comes back. Not as a punishment, and not as a test you announce, just a pause. A few people will reach out and surprise you. Others will go still, and then you get to decide what that is worth to you.
