I read links on another board. She filed for divorce based upon infidelity, abuse and irreconcilable differences. She found porn of her husband performing various acts on his computer. He apparently is also on Craig's list looking for people to participate in 3-somes and other acts. Apparently, their 7 yr old caught Daddy watching porn. Sara has also said that her husband has been emotionally abusing her recently.
Here's a link to one article http://tv.msn.com/tv/article.aspx?news=237642>1=7703
