The problem I have with that philosophy is that if I take it literally, I would stop doing the dishes, I would stop changing diapers, I would stop giving the twins their bath, I would stop cleaning up their toys, I would stop giving my wife affection, I would stop saying I love you, I would stop telling her I am attracted to her, I would stop giving her gifts, I would stop asking for a affection from her, I would stop asking for sex from her, etc. I don't want to be in that kind of relationship. Am I getting this all wrong?

Globe I do not think if you stop doing things for your children is a 180. Even if for some odd reason this helped your marriage think of how it would effect your relationship with your kids.

I think the 180 concept is more in line with how we respond to our spouses. Flitering through our personality's and actions and trying to change the ones that do not seem to be doing us any good in our relationship. You do not want to stop doing what works. Just what does not.
Just as a example of what I see as a 180 in my own sitch.
My H watches tv regularly. In a effort to spend more time with him there are certain shows I will watch with him durring the week. He sits on the couch I sit in a chair.
Last night I changed this dynamic up I took a pillow and put it on his lap and laid down on the couch to be closer to him. This is not my normal actions it was a 180 for me.

So it's not the greatest example but hey I am starting small. lol
