to get it right you have to be able to let her go (detach) and this requires confidence on your part. You and your family deserve your wife's complete attention. How you say it is with conviction that she is free to choose how she behaves and that her choice has consequences.
She chooses you she can stay.
She wants to spend her time, money, affection, energy and family resources with another man than she can go.
You have to be able to wrap your head around this to say it with conviction, confidence, composure and compassion. Your wife will test your conviction on this.
She will respect you for standing up for yourself, your family and fighting for her. she won't respect you if you are a doormat and she can push you around. We will give you the script to say to her. You have to buy into this or you won't get a second chance. Make sense?
