I used to think how it is to let go of a person loving?

It seemed to me that if you love, you will never let go, you will literally cling to the last hope, drink lips to lips and soul to soul. You will hold on to the last of your strength and pray to be kept. But then I realized that they were leaving and loving. They leave when this last hope dies, and with it the belief that something can change for the better. They leave, loving, when they understand that it is better to carry this love into their hearts, keeping good, bright memories, than to completely hate each other. People leave even loving when their strength is running out, when they realize that they have no future.
