Peter,

Most people didn’t know that their marriage was in trouble until BD. Even if it wasn’t great we just thought that was how marriage was supposed to be ups and downs. It is likely you W was slowly checking out for years. Someday you will probably look back and see it. Right now you are in the forest and can’t see the tree. She meets OM and boom her attitude changes. She has to pick fights because she has to make it seem she is leaving an awful marriage.
