FOr example: Wife: I just did the Laundry, cleaned the bathrooms, made the beds (the pauses to wait for WOA). Husband: Well, that was nice (Thinking, I really don't want that, I want to spend the evening snuggling on the couch).
So we end up with the wife doing the WRONG stuff to et WOA, and then she is disappointed when she does not get WOA.
And you get a husband who can't see his wife's actions of service as displays of her love and he continues to believe that she doesn't truly care for him causing him further frustration and resentment.
