question:  Why does the protagonist want to get back to his wife?
context: HOMECOMING BY MIGUEL HIDALGO What lasts forever? They had no place in the dust-caked, tired body, yet there they were, seeking, always seeking—searching the clear horizon, and never seeming to find what they sought. They were nearing a river; the water would be welcome on tired bodies and dry throats. Then both man and horse plunged headlong into the waiting torrent, deep into the cool embrace of the clear liquid. Refreshed and momentarily content, he sat staring into the dying fire, seeing the bright glowing coals as living fingers clutching at the wood in consuming embrace, taking all and returning nothing but ashes. Images began to appear, drawn from inexhaustible files, wherein are kept all thoughts, past, present, and future.... World War III had been declared, and he had enlisted, receiving his old rank of captain. He held her very close, feeling the warmth from her body flowing into his and making him oblivious to everything except that she was there in his arms and that he was sinking deep, deep into a familiar sea, where he had been many times before but each time found something new and unexplored, some vastly different emotion he could never quite explain. When he opened it, he found a picture of her in one side, and in the other a picture of the children. He took her in his arms again, and loosened her long, black hair, burying his face in it for a moment. Then he kissed her, and instantly was drawn down into the abyss which seemed to have no beginning or any end. Three days later they had landed in Spain, merged with another division, then crossed the Pyrenees into France, and finally to Paris where the fighting had begun. Three years later they were on the road to Moscow. The Russians had not yet used the H-bomb; the threat of annihilation by the retaliation forces had been too great. They were bound for bigger, more important targets. When the all-clear had sounded, the men clambered from their shelters.
