Did your child get shit?This is a slippery slope
Had she told the dude what the situation was upfront, who knows what his reaction would be. She took away his power of choice.
Where does it stop though. What if she takes any support she gets from him to spend on the other kids. You're taking advantage of him taking care of his responsibilities while not holding the other two dad's accountable for their lack of monetary contributions.
Did they go without?
Get out your feelings.. It's for the kids, not you.
Clearly dude and the mom ain't always on the same page. That's why they not together now, right?
Pick your battles... This ain't it
