What incidents in the novel reveal that Leonce may not be a good husband for Edna?

Leonces's flaw as a husband is the result of his belief in
the traditional roles of Acadian society and of his unwillingness and inability to
communicate effectively with Edna.

As a "traditional"
Creole gentleman of the times, Leonce believes it is his duty to provide financially for
the family and it is Edna's duty to be devoted to him, their two children, and their
home. When Edna suggests she is not interested in these domestic duties, Leonce is
almost incapable of comprehending what she means. In his mind, this line of thinking is
utterly ridiculous. In short, Leonce does not think of Edna as an equal partner in
marriage or in life, he thinks of her merely as another member of his
employ.

Against that backdrop, Leonce's inability to
communicate effectively with his wife exacerbates the problem. When Edna shares her
feelings with Leonce, he dismisses them. When her behavior contradicts his expectations,
he dismisses them as well, choosing to believe that it is simply a phase through which
Edna will pass. By dismissing Edna and her concerns and never communicating with her
about them, Leonce severs any ties that exist between the two.
