if your financial situation changes, you can petition the court to revise your support order. your ex sure as shit isnt going to, unless your financial situation improves, and as far as the court is concerned the filed support order is what stands, unless it is challenged and changed.  thats likely a dude who tried to be civil with the mother (agreed to her demands) for the sake of the kids, and/or he doesnt know that support orders can be amended, but you have to file with the court to change them. tl;dr: dont be a retard, and hire a fucking lawyer.
