My two cents:
Both of them are selfish and just out for the money here. Kate is a tyrant who wants to control everyone and everything around her. She had a huge fight with her partner the first week of DWTS because he didn't just roll over and take it like Jon did all those years. She was actually trying to tell him that HE, THE PROFESSIONAL DANCER, was doing it wrong, and started the whole crying, my life is so tough bit when he called her on it and told her to shut it and take direction. It has been an ongonig problem from what I am seeing from rehersal footage. She is always bossing, and then crying when she is not allowed to run the reherasl. She has got to learn to let go and stop trying to tell everyone around her what to do, and when and how to do it. That is at least part of what ended her marriage. Jon needs to stop chasing tail and trying to be famous and get a real job. He spent entirely too much time buckling to Kate and just taking it before he lost it completely. Taht doen't entitle him to a second childhood. He needs to get over himself, grow a backbone, and start being a man. Both of them need to step OUT of the spotlight, downsize their lives, and try to live like normal people. If not for their own sakes, then for their children. Thise children really do not need to be on tv any more. They have enough to deal with. The problem is that they have gotten too used to living the way they do. I think they feel like they cannot give up the multimillion dollar house, designer clothes for all of them, $8000 hairdo's ect. They have to come to grips with the fact that they can and need to give up those things and try to live a normal life for the sake of their children.
