Ex wife and child support...

I’m kind of SOOOO annoyed right now. I’ll try to keep it short. My husband and his ex wife have two kids together. Court order says 970$ child support a month. Since she kept begging for more and we felt bad because she lives in a one bedroom apartment with the kids my husband pays now 2k !!! A month. He is 10 months out of the year deployed and never sees his kids so now hes home on leave and we have both of them here... for little over a month. So now she called asking him for her 2K child support... i told him he should give her only 970$ just like the court order says because we have the kids this entire month !! Just because she lives a high life partying 4 days out of 7 and never does something else and she can’t afford a better place because she spent a everything on partying that doesn’t mean we have to finance HER... now she pissed him of and he’s mad at me because I said not to pay her the 1K extra... sorry but he can be pissed as much as he wants but I’m not going to finance he BS while I have to sit down and write down where I spent what because the money is short since she gets payed way more she should get...
