S, The comments that I posted to Steelersfan where for her situation because she and her h are both cleaning their homes at this time and it's purely coincidental that it's happening that way. My comments to Steelersfan did not come from a book, but from my own thoughts and observations.
Many of them have to do an internal housecleaning of their demons before they can return. Keep in mind, they have to grow up, learn that happiness comes from within and accept themselves for who they are, not what they were suppose to be for their parents or authority figure that was in their lives many years ago who stunted them emotionally.
SF was housecleaning her actual home. Housecleaning keeps you, the lbs, busy and keeps you focused on something other than your spouse. We all do it at some point. You do get tired of things being the way they were, i.e., just like fall and spring cleaning.
