If he and the other three sons are really behind her like she claims then I wonder why he would file the papers now. It he is "supportive" then it is extremely poor timing to have divorce proceedings coincide with the week she is in the media spotlight.
From interviews Cindy has given, she's basically destroyed her family in favor of her own 'needs.' She's on the road at least three weeks out of four. Her husband had enough and left. Her youngest daughter (19) has drowned her grief in drinking and partying. Her eldest daughter and surviving son see, to be doing okay from what she says. But she can't be there for any of them because she has to 'save the world' from George w. Bush.
