Love never dies a natural death. It dies because we don't know how to replenish its source. It dies of blindness and errors and betrayals. It dies of illness and wounds; it dies of weariness, of witherings, of tarnishings.
But then, life is a constant withering of possibilities. Some are stolen with the lives of people you love. Others are let go, with regret and reluctance and deep, deep sorrow. But there is compensation for lives unlived in the intoxicating joy of knowing that the life you have - right here, right now - if the one you have chosen. There is power in that, and hope.
