This is like an irresistible divorce busting quiz. These are my answers:
1. You say to the spouse, "Oops, I accidently changed all of the locks on the house and forgot to give you a key.
2. Fantasy fog can only be cleared by a special pixie dust or a huge leap in personal growth that usually follows the realization of a great loss. An example would be the loss of everything the person holds dear (and that may not be enough).
3. GAL for yourself, not your wife. The end result should be that you're having a ton of fun and moving on with your life.
