1. Go to a place that is buzzing with activity and somewhere you have never gone before it will help fill the silence. Look up the menu online before hand or call ahead and ask what they recommend for good combinations of appetizers and main courses. Order new dishes that you never ever have. Act like you know the place. If she asks if you have been here before smile and say that "this is really good". She will think you shared an experience without her. Keep your answers vague. Act like she would.
Did I say how you are going to look. New outfit. New smell and a haircut. If you shave get a barber to do it for you. You are going to look like a million dollars. Every time she talks to you. Look her in the eyes and smile and listen. And talk small talk. If R talk comes up. Say " I will have to think about that " And leave it at that. If she keeps it up set up a boundary that you do not want to hear it tonight.
Then when she is all in the zone and brings up OM and shoves it in your face.
You have a choice keep it easy and breezey or you start to lay down the law. 1. She is going to pull her weight around the house. 2. She is not going to speak to OM in the house any more. 3. She is not allowed to have OM around the children at any time. 4. You will no longer be part of a marriage that includes a third party. 5. If these boundaries are broken she will be on the street.
Choices. But you know what. Either way. That is the night you take control of your families life.
No where do you tell your wife you want her back or talk about good old times.
