Moving away is a stress test for friendships. The real ones reroute; the rest just go quiet.

Distance does not end a friendship, it removes the part that was running on proximity. Some of what you had was built on seeing each other daily without either of you choosing it. Take that away and you find out how much was actually choice. The ones that reroute are the ones where somebody keeps doing the work of staying in touch.

Whether you left or stayed, pick two people and put something on the calendar instead of promising to catch up soon. A monthly call that happens beats constant messages that fade. If one goes quiet, that is not a betrayal by either of you.
