So does this story ring true for you? So, he has not called in a week nor does he answer calls. Voicemail messages are never recorded (the phone rings and rings).
It is a tough call to determine when a relationship has reached the end of its lifespan. When is it necessary to bail out or adjust the terms of engagement? Needs change and expectations dwindle. There may still be love but the need "to be together" has faded. Friendships have boundary lines. There are unsaid lines drawn in the sand. The desire to move a relationship forward could be negated by the other party's unwillingness to go with it. Perhaps they lose interest. Or they got a bad vibe. People are super sensitive. We process subtle messages and act accordingly. The pain of separation is equal to the amount of initial energy and time invested.
If it is a friend you only met recently and oddly the relationship ends because she moves away, the pain of separation will probably not be as great as a friendship cultivated throughout many years that suddenly terminates.
The lyric from the Sondheim song "every day a little death" makes sense when one considers the many times love is given only for it to eventually subside and cease to be. Every day there is a little death, not only in our bodies but in the course of our relationships.
