Walkaway wife syndrome is a term used to describe women who suddenly leave their marriages without any warning or explanation. The term was first coined by Dr. Steven Stosny, a therapist who specializes in helping couples heal from the pain of divorce. Walkaway wife syndrome can be caused by a number of factors, including unresolved marital conflict, infidelity, financial problems, and even mental illness. While there is no surefire way to prevent walkaway wife syndrome, couples can take steps to improve communication and resolve conflict before it reaches the boiling point.
