You now have the option to stick to an existing arrangement but if you are really honest, you have to concede that you no longer have the desire. You see life differently now. You can't deny what you consider to be important, nor can you pretend to yourself that this isn't vastly different to the priority you held in the past. The coward's way out involves dragging your heels, deliberately allowing a situation to fall apart and then blaming it on 'circumstances'. Don't. You can afford to be brave and to own your new decision.
