Exactly what Courageous said, Coda. My WW wanted the same thing. And I even went so far as to try mediation. A waste of time and money. I ended up filing and now it's war.
Other unfortunate similarities: WW wouldn't give up the AP, we separated (do it ASAP), no-fault state...
All I thought I wanted and she wanted was was joint custody and half of the assets, too.
Once I filed, all remaining reason and "good intentions" went straight out the window, and she revealed her true colors. (Stupid me.) It's gotten real ugly real fast.
Retain your own lawyer. Now. Read my thread if you want to see how my story went and is going.
All the best to you. You have made the right decision to separate and divorce. (I hate to write those words, but I must.)
