I never thought that the definiation of Left Behind or Walk Away indicated the one who physically left the home. I always felt like it referred to the one who emotionally left the marriage.
My sister was married for over 30 years. The last 5 years of her marriage they had seperate bedrooms and seperate lives while her husband openly carried on with OW. Neither one of them wanted to leave their home but it got so bad my sister needed to regain respect for herself and knew she couldn't do that living in that situation...so technically my sister is the Walk Away but is she really?
