What are the motifs in Astronomer's Wife by Kay Boyle?

An "epiphany" is a sudden moment of clarity, often brought on by emotional stimuli or by very minor events. In "Astronomer's Wife," Katherine Ames has an epiphany about her husband and what he has done to her. She wakes up on this day much as she does every other day—alone. The prose of the story gives a sense of deadness, as the author's style is quite flat in the early part of the story.
