I was smiling as I read the exchange between you and D7. They get it at whatever age that no matter what cheating is wrong. It is a shame that the OW isn't as mature as your daughter in the morals department.
Something that I noticed about the OW trying to win over your family. I think it is more for her and her poor self esteem rather than for your H. I doubt she really considers anyone else in what she is doing.
And I am curious about how the OWs relationship with her own father is? She comes across as childish (in my relatively narrow view of the OW) and needing your Hs acceptance. Her fear of your H finding out about the scratched window is more of a child's concern of the possible wrath from a parental figure.
Hmmmm
