A spouse who is done and S who has a bf or gf isn't wayward they are simply moving on. They are done. Especially if D papers are filed.
What about a spouse who left a marriage where there was still a lot of love between the two spouses, because the spouse met someone they thought was better, but the person they met is a dead-end road -- a fantasy life, of turmoil? (Two cheaters paired up together, a relationship with a co-worker, the guy has a wife, that doesn't seem to have much income, and four kids, and is Mormon, though the WAW isn't.) Isn't this spouse a wayward even after she left and sought complete separation? She has all the characteristics of a wayward, for the most part, I think.
