What is the resolution to Krebs's conflict?
The resolution is when Hemingway's anti-hero, Harold Krebs, who resolves his conflict by abandoning himself to his disillusionment, leaves home because he wants his life "to go smoothly."
After having suffered through the horrors of World War I, Krebs simply wants to relax at home, but he soon discovers that he cannot relate to the people who want to hear lies about the war. Previously, Krebs has been able to follow a code of honor which has given him a sense of "valuable quality," but now because of the lies he has told, he has a certain "distaste for everything that had happened to him in the war."
The new complexities of his life are overwhelming for Krebs, so much so that he feels completely inauthentic whereas during the war he was, at least, able to do "the only thing for a man to do." So, after he feels forced to lie to his mother, Krebs feels that there is nothing for him to do but leave home because he wants his life "to run smoothly" so he can keep his life "from being complicated."
