That he had a child from a previous relationship and that he had to pay child support. The amount hasn't went up in 5 years. No, it didn't go down just because you decided to have two children either. I am sorry you make more than him, I know $500 seems like a lot for one kid, and I know that you don't really care for the mom. But this isn't anything that is new. This was the situation when you said "I do" so why is it such a problem now??? Oh, because she is married to a great guy and gets to stay at home and you don't??? Or because you wanted a girl and had boys?? Or because now you make more than him??? Whatever the reason is, I can't hear one more complaint about it!!! Do you have friends that constantly complain about a situation they created??? What do you do???
