Just a trip down nightmare lane when I first started dealing with stanch Disneyland Dad and his "if I can't come first 100 percent then my spawns will come first over your serious relationships" mentally unstable breeder. 
 

I remember this itchB traipsing back in town with her spawns, moving 5 minutes away, then pretending like she couldn't parent her kids.   Nothing was wrong with her except Disneyland Dad enabled her trifling behavior "for the sake of those kids". 
 

A couple of incidents where she refused to pay her electricity bills, her car payments, claimed not to have grocery money, etc. 

White knight Disney dad would always come to rescue his beastly breeder in "distress" 

I was on the verge of calling her bluff and filing an anonymous CPS report but then I realized those domestic t3rrorists would end up in my space destroying my peace 24/7

I felt so relieved during a couples therapy session where I informed the therapist about this heifers effed up behaviors and the therapist called his ass out and said "have you given your ex wife money outside of your child support agreement"

First he lied and said no but then I pulled out receipts and he admitted she "needed" "grocery money" "clothes" etc

Therapist called him out again and eloquently told him that child support money is for necessities and it's her responsibility to make that amount work and if she cannot then she needs to apply for government resources and if she is intentionally neglecting kids needs after being provided child support / knowing how to access welfare then she needs to be reported to CPS. 

He didn't dare argue with that therapist like he tried to argue with me and gaslight me so many times. 
 

Call their bluff and hold these breeders accountable for neglecting their kids .... if you don't mind those kids landing in your home permanently and if you know the kids are truly suffering.
