Distance can reveal which relationships had been maintained mainly by a shared location.

Some friendships are held together by proximity and some by intention, and while you live in the same place there is no way to tell them apart. A move separates the two very quickly. People you assumed were central drift, others you never counted on keep writing, and the sorting can feel like a judgment on you. It is mostly a fact about how each connection was built rather than about its worth.

If a move has quietened certain friendships, allow that some were of the place, which is not a failure. And when someone keeps in touch without being nearby, notice it and answer.
