Some people seem to exit their vows nicely. They divorce successfully. They laugh at their childhood vows in the sanctuary. They move on. For others, the old vows are dragged along like an anchor.
Psychiatrists attempt to untie the knots that hold on.
Or worse, the vows drive their makers to compensatory behaviors. We make vows and promises with best intentions. Some are good and possible to keep. Others were right for us at the time, but no more. It takes courage sometimes to face up to the need to redo one's vows.
