In a situation like this, I'd say that revenge is a dish best served tepid.
Patience truly is a virtue, anger hardly ever gets things solved. As has been said before, CPS. You say your attorney is also a judge, I'd ask him for the advice of a trusted fellow attorney who specializes in men's rights when it comes to dependable dad/deadbeat mom scenarios. It's horrible that these days men don't always act like men and the legal system favors women when it comes to custody even if they're complete ass-hats in the parenting department.
Don't give her any ammunition to shoot back at you, it will be exponentially difficult but poker face, poker face, poker face... Smile, nod, but make sure everything, even phone calls etc are documented, photographed, and what transpired dictated. Slow and steady wins the race.
Good luck to you brother and my heart goes out to you and your little one.
P.S. What'd you use to nab those squirrel? My Ruger 10/22 is sitting by the door and begging to go outside and play...
