Sorry, I wasn't really talking about him, since, as you said, he did not leave his children. I feel for him, I really do, especially since he is sticking it out and trying to do the right thing. I also agree that sporadic OT shouldn't really count against him. I think what previous poster have said, where the income is reviewed annually and the child support is adjusted accordingly, sounds more reasonable to me.
I do agree with the PP that you should be careful what you post on the internet. I'm totally not being snarky. I work in payroll and know you have to be really careful about what confidential information you put out there, even when you don't mention a person specifically by name. Messages boards aren't always as anonymous as we think they are. I also work for a municipality and always have to balance employee confidentiality and the Freedom of Information Act. It's not always easy.
Oh, I totally get that. Which is why I said I'm not impressed with any of these parents (moms or dads). Dads totally have the right to fight what they think is an unreasonable amount of child support, especially when it causes them to be unable to take care of themselves. Now, if we are talking about dropping the first kid because they can't take care of their second family, that's another story. They can fight all they want, but don't dump the kid. Would they walk if the child had huge medical bills to pay? Or a child with emotional disabilities that can make life a living nightmare? Just like those cases aren't the child's fault, neither is a money grubbing mother or one who's emotionally disturbed.
Mother's also have a responsibility to not rake the dads over the coals and too treat the ex respectfully.
