>>5193964Divorce is my first instinct. Cold, unshakable instinct. But I'd play it smart and consult with an attorney first to see what my chances were. A divorce can play out in numerous ways depending on where you are in life financially and otherwise. Also, the age of the child and number of years married certainly come into play. And that's saying nothing of the laws of your state.
In a situation where I knocked a girl up, did the right thing, and found out a couple of years later the kid wasn't mine...oh, it's on like Wrestlemania.
