Are there many things in the pursuit of happiness more terrifying than the ability to get over somebody?

The nature of overpowering feelings is such that one cannot live with them without them to change their life. In most cases the change is impossible, because, as the saying goes, people don’t change. They are rather changed by the people who truly alter the nature of their life. When these people elect not to come into your life, the potential change is left stagnant, bursting uncontrollably into random elements of your life, until it simply has to be brought in check.

Is this part of the self that is inseparably vested in the person we permanently remove from out existence any less deserving to persist though just because we fail to find a controllable use for it? Some say that the ability to admit an ending, to turn around from a dead end and find another way up the mountain of life is admirable and powerful... but isn’t it horrible? To have the ability to cut out an aspect of the self, and do it again and again and again, just so the remainder can continue the journey? How many potential yous can you murder before the present you is no longer the traveller, but rather just the travail of the journey, where each action is designed to perpetuate it long after all the goals have withered away down the cul-de-sacs of necessarily-abandoned possibilities?
