I'm surprised by some of these responses. Marriage is about two people coming together to build a home, with that comes responsibilities; whether they existed before or after marriage.
You can't pick and choose your obligations to suit you. Just as if your husband has debts, upon marriage, they become your debts. If he had an illness before meeting you, that becomes your responsibility to care for him upon marriage. What if as a result of the illness he couldn't work? Will you refuse to pick up his obligations?
We talk so often about deadbeat dads and here's someone who is doing the right thing and yall are acting like he's some leper. What if your husband couldn't afford the CS payments anymore? You're going to refuse to help him put food on his child's plate? This is a child we’re talking about. It’s your duty to help support this child as a compassionate human being. This child will be your future child's (if you have any) sibling. You owe a duty to that child as well if for no other reason than that.
Some of you are on some straight B.S.
Bet you claim to be Christians too huh?
And in anycase as others have pointed out, if he's paying child support, that is joint income that is being taken away from the home. Just because you're not reaching into your pocket book to pay doesn't mean you're not paying.
