You guys keep blaming Jon, and while he may very well be equally responsible, we do not know the entire story. According to Kate's family, Kate called it off a while back but told him he had to keep living at home and keep up the act for the cameras. So if that is true, he wasn't cheating on her as they were already separated. He just got caught when he was supposed to be quiet about it. That's probably why he's not been as apologetic. It's also where the "Standing up for himself" comment came from. He doesn't want to do the show and she does. Why would anyone force their spouse to participate in the production if they don't want to? If they were careful with their money, they would easily have enough for college for the kids - they make around $50,000 a episode. Her book deal paid for that house (which is gorgeous, but they could have bought a 5 bedroom house for half as much if they were so worried about money.)
Also, Kate has like 11 "helpers" - chef, nanny, laundry service. She's not doing this alone but she sure wants you to think she is. She is playing the victim.
She spends 20 days a month on her book/speaking tour. Watch their interviews and notice how all Kate says is "the show must go on" and Jon just keeps talking about how he's going to see his kids. You can also see their interaction - Jon plays with and enjoys his kids, Kate seems to find them to be props at best.
Of course everyone wishes they would work it out for their kids. But anyone who has seen the show can see that they do not get along. They need to stop the show, focus on the kids, and stop lying to the public and people will stop caring about their every shopping trip. The media only became interested because it was a scandal - because they were lying to their audience. If they come clean and stop lying they won't be on the front page of the tabloids much longer.
I agree about the "guest stars" How about Supernanny?
