The Silent Wife

This novel is not what it appears to be: it is not a standard mystery or juicy suburban thriller. If you are looking for a mainstream Ruth Ware/Liane Moriarty/etc., this novel is probably frustrate you.
This is a novel about secrets and choices and keeping your mouth shut when you should speak, and being passive aggressive when you should be assertive, and doing these things over and over until
It is too late and you can't take them back and violence occurs. The main characters both do this, and one of them has done this before as well, in their past—keeping silent and choosing the passive aggressive route of the silent treatment.
The intertwined milieu of therapy greatly interested me, both as a (retired—I am disabled) therapist, and as a therapy client. The author gets technical about therapeutical theories—Jung, Adler, for example—and in doing so really enhances the novel.
