Don't try and figure him out right now. He's in a fog and not himself. You'll only drive yourself crazy. Instead, focus on being a wife womanonly a fool would leave.
There; fixed it for you. ^^^
Seriously, it's an important distinction. As harsh as it sounds, Zimmy's husband has basically "fired" her as his wife right now. Through GALing and the other DB principles her job is to detach and portray herself as a WOMAN that any man would love to have, while communicating to her husband that while she doesn't WANT a divorce, she respects his wishes and she realizes that she's going to be okay as she begins to move on.
