Relationships - of all kinds - are like sand held in your hand. Held loosely, with an open hand, the sand remains where it is. The minute you close your hand and squeeze tightly to hold on, the sand trickles through your fingers. You may hold onto some of it, but most will be spilled. A relationship is like that. Held loosely, with respect and freedom for the other person, it is likely to remain intact. But hold too tightly, too possessively, and the relationship slips away and is lost.
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 withering, of tarnishing.
