Ken, you make sure you can leave her alone and not be pleading with her to return to you once she leaves. If you don't have the stength to stick to it...don't try b/c she will really be bad after that. Don't do this thinking it is a gimmick to get her back. Do it b/c she is dishonoring the M.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
