You can feel a friendship ending when every hangout starts feeling like a rerun.

The signal is not an argument. It is that nothing new is getting added: the same stories, the same three jokes, the same shape of evening, both of you playing a version of yourselves from two years ago. Friendships run on fresh material, and when the supply stops the time together starts feeling like watching something you have already seen. That feeling is information, not a crime.

Before you decide, try changing the setting once. Do something neither of you has done. Sometimes the rerun was the format rather than the friendship, and if not, you find out gently, which is the better way.
