The WAW, IMHO, does not have the cold, selfish heart of the WW. She is not directed by selfishness. She does not have a hidden agenda that involves an affair or random sexual partners. You don't see her moral integrity dip, like you see in a WW. She doesn't go crazy, try to dress and act like a teenager, or act like GGW. She doesn't breakup the family out of sheer selfishness. She either leaves b/c her H is abusive; is imprisoned; involved in some type of illegal activity; is too controlling, jealous, etc; has an addiction........or something that pushes her to leave him in order to survive. In other words, her leaving can be seen as justifiable.
Thanks, Sandi. These descriptions should be pinned somewhere!
