I know exactly what you mean. My WAW also is not the same person I married. She didn't change overnight, but she definately changed. I sensed over the past couple of years her sideways drift. She became unhitched from me, more independent, lost respect. All you can do is open the cage and let her fly away. Maybe the person you married will some day come back. Or not.
