The Bride Comes to Yellow Sky

The opening setting of this story takes place on a train traveling from San Antonio, Texas to Yellow Sky, Texas. The protagonist, Jack Potter, is seated with his bride on the train. While they are happy about their marriage, they are worried about their future together in Yellow Sky, which is Jack's hometown. He is the town marshall of Yellow Sky, but he hadn't decided to tell anyone of his intentions when he left for San Antonio. His main duty in town is to fight with Scratchy Wilson when he gets drunk to help prevent him from injuring any of the townspeople. As Jack and his bride are nearing his home, they spot Scratchy Wilson in the street. Scratchy was looking to fight Jack, but suddenly backed down once he found out that Jack had gotten married. Scratchy said, "I s'pose it's all of now," and walked away. It seemed as though Scratchy realized their fights were childish and now that Jack was married, he needed to move on with his life. Scratchy seemed disappointed that their fighting came to an end.
I didn't really enjoy this story very much. I don't understand why Jack didn't tell anyone in his town that he was going to get married. Would they really be upset? Would they be upset because now he wouldn't be able to fight Scratchy when he was drunk to protect them? Or would they be upset because this was how they were entertained? The story seemed a little confusing to me and it didn't seem to really capture my attention like I hoped it would.
