why are you paying child support for kids that live with you??? That makes zero sense. After you pay your child support the money you have left goes towards your current family which INCLUDES THE CHILDREN and bills. She's not "paying for the kids" she's using your "not really child support payments" to pay for stuff so YOU'RE paying for the kids (unless I'm misunderstanding something). You guys aren't divorced, why is she acting like you are? And you’re paying child support payments for three children for Hannah but you and Stacy only have two so it’s not fair that you pay just as much to Stacy as you do to Hannah because she's got a whole another kid. The whole thing is weird tbh. . . NTA I guess?
