You can outgrow someone without making them the villain. Growing apart isn’t a crime scene.

Not every ending needs a reason that would hold up in court. People change at different speeds and in different directions, and sometimes the overlap that held you together simply runs out. Inventing a betrayal makes the distance easier to explain and much harder to carry. The plainer truth is that you both moved.

If a friendship has gone quiet, let it be quiet without building a case. You can be glad for what it was and still not force the next meetup. Say something kind about them the next time their name comes up.
