Yes it's mind reading but it's also what ALL WAS do! They are not interested in handling the particulars because that is messy and real.
It's very interesting and something I have been fascinated by for some time. If you follow most LBS they are far more involved in the legal process (as in more hands on with research, looking for alternatives, asking questions) than the WAS.
It fits the behavior pattern - the WAS doesn't want messy, they want out and it's VERY ideal to let a third party handle the unpleasant parts. It's one of the very reasons it is not always ideal or easy to "work" with a WAS when it comes time to settle. That means facing this big old pile of crap head on and that is what they ran from the first time around!
I am not suggesting you sue this woman for everything in the world but this is an area where she should be given NO leeway to "lead". She had decided what will happen to the marriage but she certainly isn't the only person in a decision making process where the children are involved.
