What is the main conflict in The Dog of the South by Charles Portis?

The conflict is presented as two-fold. Obviously, there is man versus man, as Ray pursues Norma and Guy in order to retrieve his property and, perhaps, convince his wife to return home. There is also man versus self, as Ray engages in some amount of introspection, analyzing why his wife prefers Guy to himself and his failings as a husband. These two conflicts will be developed over the course of the novel and resolved.
