When Ross' husband Sanders stepped out in public on July 30 following the highly publicized affair, he was wearing his wedding ring. It is rumored that he is still committed to fighting for their seven-year marriage after photos surfaced of him cheating with Stewart in US Weekly.

According to Radar Online, "Liberty is not making it easy for Rupert."

Sanders told his closest friends that he has made "the worst mistake of my life," according to a source. He also fears that the mother of his two children may file for divorce.

"She is refusing to see him right now and has not spoken to him about if they have a future together or not," the source added.

According to several reports, Ross has banned the 41-year-old film director from working with Stewart on the "Snow White & the Huntsman" sequel.

Liberty Ross told her husband that the only way their marriage could work is if he gave up working with the 22-year-old.

"Liberty let it be known in no uncertain terms that Rupert can't direct the sequel to Snow White and the Huntsman," Radar Online has also reported.

Ross played Stewart's mother in "Snow White and the Huntsman." When the 22-year-old's affair with Sanders went public, the former model tweeted, "Wow" before setting her twitter account to private.

According to BBC, the former model posted a picture of a beer-drinking Snow White on her Instagram account with the caption: "Not so pretty or so pure after all ....."

Sanders later issued an apology statement which was posted on PEOPLE's website:

"I am utterly distraught about the pain I have caused my family.  My beautiful wife and heavenly children are all I have in this world. I love them with all my heart. I am praying that we can get through this together."
