问答题 ...He realized that these walks amused neither of them, but he could not bear to leave her, and did all he could to lengthen them till she became tired and out of temper. He knew that she did not care for him, and he tried to force a love which his reason told him was not in her nature: she was cold. He had no claim on her, but he could not help being exacting. Now that they were more intimate he found it less easy to control his temper; he was often irritable and could not help saying bitter things. Often they quarreled, and she would not speak to him for a while; but this always reduced him to subjection, and he crawled before her. He was angry with himself for showing so little dignity. He grew furiously jealous if he saw her speaking to any other man in the shop, and when he was jealous he seemed to be beside himself. He would deliberately insult her, leave the shop, and spend afterwards a sleepless night tossing on his bed, by turns angry and remorseful. Next day he would go to the shop and appeal forgiveness.
