How do the scenes in Elizabeth's apartment become predictable in the novel, Want?

Almost all of the scenes occurring in the apartment are replicas of one another. Elizabeth climbs down from her loft bed every morning, returns from her run, has sex in the bathroom with her husband, and rushes out to work as he gets their girls ready for school. Whenever she returns home, her husband is making dinner, and asks about her day. The apartment is a fixed setting, in which predictable daily events elapse.
