Norm, my wife also gave me her grand plans of being the best of buddies after the Divorce. Going so far as to telling me her plan was to sell our house get side by side smaller houses and have the kids go between whenever they wanted. She was shocked that I responded to her by telling her to get out of la la land that that was not going to happen.
The WAW really gets to thinking about her decision making only when her master plan does not go the way she wants it to. For example, she had no idea that after I told her how I felt about the whole situation and how I thought about her throwing our marriage and our kids under the bus, I would start going to the gym and start to get in better shape (with a hot little trainer named, Wendy!). She did not know that I would start to go out with friends at night and have a great time by myself! She had no idea that I would not move out of the marital bed into a guest room. (actually had move back into bed after taking advice here). She had no idea that I would get a new haircut and start wearing some new cologne. All of this went against her plans of leaving this looser of a husband and still have his friendship and fatherly help at her side. It was a wrench that stopped the wheel.
Time to start taking advice from these people, buck up, it gets bumpy, but it does work, and I am proof.
