Newsflash--takes two to tango. Now I will say that there are a lot of couples where there is a jilted spouse where one cheats and the other is the last to know, but in my experience it's a lot more common to see BOTH partners ****ing around on each other. Again, not universal, but far more likely than not.
That being said, WTF is the daughter's issue? How the hell is the husband getting ANY visitation with a no-contact order in place, unless he took it out on HER, and the courts decided SHE was an unfit parent, which given the bias in the family court system is saying a hell of a lot.
