DNA & divorce: When the adulterer’s dirty little secret gets exposed

So you slept with someone other than your spouse and you got pregnant. That is definitely a double whammy.
It’s bad enough you are sleeping with someone other than your spouse. But to get yourself knocked up on top of it, that is almost unforgivable. But what is really off the charts is proceeding to try to pass the youth off as your spouse’s child and then after you divorce said spouse, forcing said spouse to pay child support.
I was reading a story on the New York Times about how DNA proved a man’s daughter was really not his (so he divorced the mother who then married the real father) but the courts forced him to continue to pay child support.
That’s dirty.
