Good Parent, Bad Spouse

I was watching the View and they were having an argument about spouses having an affair. It all started with the Rosie/Donald arguement where she said how come he gets to be the moral code for Miss USA when he cheated on his spouse and has been married 3 times. Then Barbara said something about a "little affair." The blonde (can't think of her name) got upset over the word "little," an affair is an affair. Obviously Barbara has never been cheated on because it's never "little." Anyway, the blonde said that if you are a bad spouse then you are also a bad parent. Now Rosie disagreed on that one, even though she said Donald Trump was not a good moral code. She was saying there was a difference between the two. You can be a bad spouse but a good parent. I disagree. If you are having an affair, even if it's a brief one, then you are not being a good parent. First of all, you are cheating on that kids mother or father. If the child finds out (and trust me they will find out one day) what does that tell them? That it's okay to treat their other parent that way? That it's okay to cheat? Isn't that was Joseph Kennedy taught his kids? We teach our children by example, so what type of example are you teaching them? Bottom line, they're watching you and emulating you.
