20k is too fukking much and she wants more?
For one daughter? You cannot be fukking serious. I would try to get primary custody and cut her off, not out of love for the child, but out of spite for her ass. Kids out here being brought up for less, and we know that 20k is being spent primary on shyt only very remotely relating to the child.
100k?
If he broke her off 40k a YEAR that child would be eating good. He should bury her in court. I sure would.
Call me petty, but i would try to bankrupt her and send her back to where she came from before me.
