Why is curley always running around looking for his wife in the book of mice and men?

In the novel "Of Mice and Men" by John Steinbeck, it is not so much that Curley is always running around looking for his wife, but rather that his wife is often wandering off and getting into trouble, which leads Curley to go searching for her. Curley is a ranch hand on the farm where the story is set, and his wife is often seen as a troublemaker and a source of tension among the ranch hands.
