To follow up on the subject of NC with your W, and the advice from D14's IC...….are there times during the 24 hr day that you and W are together in the house? I was wondering if D14 sees Mom & Dad not speaking to each other or giving any acknowledgment of their presence when in the same room. If this is the case, the atmosphere must feel very tense for everyone. It makes for some uncomfortable times around the dinner table.
This is just my opinion. If you have kids and are staying under the same roof, then for the sake of the children show a little interaction with the other spouse. Say hi, bye, pass the salt please, or something...…..just as long as the other spouse is decent and doesn't show some type of disrespectful reaction when you open your mouth.
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!
