After a friend group breaks apart, the empty weekends teach you what you were only doing to fit in.

When a group comes apart, the empty time afterwards shows you what you were doing because you liked it and what you were doing in order to stay included. Those two are nearly impossible to separate while everyone is still going along, since the plans arrive already made. The quiet is uncomfortable, and it is also the clearest audit you are going to get.

If your weekends have gone silent, spend one of them on something you chose entirely by yourself. Notice which old habits you do not actually miss. Build the next group out of whatever survived.
