Stay With Me is something of a depressing read, exploring the conflicts within a marriage. We see the views of both husband and wife, but I never really got the feeling they were together.
When we first see the couple they are welcoming family into their home, and the mother-in-law is making plans for her son’s second wife to live with the family in order to increase the chances of him having an heir. This is a difficult concept for me to get my head around, and it’s clear that neither party is that interested in bowing to familial pressure (though for different reasons).
As the book continues we see the pressure they are put under to conceive. Our female character even experiences a phantom pregnancy, such is the pressure she feels to have a child. As things progress she bows to family pressure, and it doesn’t come as much of a surprise when she finds herself having sex with another man (her brother in law) in order to conceive.
From the outset I couldn’t understand how a couple supposedly so in love with one another could be so divided. They don’t share their thoughts or feelings, and as the book continues we learn that the strains on their relationship are on both sides.
While I initially had sympathy for our female narrator, her behaviour was hard to condone. Even when we learn of the betrayal set in motion by her husband it still felt too much to see either of them as anything other than willing participants in their seemingly inevitable destruction. 
By the end I felt overwhelmingly frustrated by the cultural and societal expectations that seemed to create this rather twisted situation.
