In any of these scenarios, you change how you treat her. You do not offer intimacy, you do not tell her how you're feeling or what you're thinking. The less she knows about your mental state the better, make her wonder. You don't make dates with her, you don't do acts of service, you go out and GAL your ass off. You treat her as a friendly co-worker. If she asks you to do her a favor and it's not a major inconvenience, you do it. If it's a major imposition, you don't.
You lovingly detach. i.e. if you are not committed to me as my wife, then you do not get any of the benefits that come along with that. Then, you make those benefits that she is missing compelling through your actions -- you become the man that only a fool would leave, but she is not allowed to have.
