My goal is to model healthy adult behavior to my children. They are watching.....
Model it when speaking/interacting with my (x)spouse. Model it when speaking/interacting with each of my kids. Model it when speaking/interacting with others.
Continue to learn better adult behaviors.
Unfortunately, the only thing that got through to my wayward W was when I essentially cut off all communication. Even when we were in the same room, I would not look at her, and would only answer direct questions, with one or two word answers. After a few months of that, she indicated she wanted to reconcile, and she became extremely affectionate. I did then break down my wall and started treating her very well, I was fun and charming, and affectionate in return. Result? She told me she was confused as to how she felt about me, and now we're back to barely speaking.
