Snow White and the Huntsman director Rupert Sanders is desperately trying to save his marriage following revelations he cheated on his wife, Liberty Ross, with Kristen Stewart, RadarOnline.com is exclusively reporting.
Sanders has confessed to friends that he made "the worst mistake of my life" as he fears his wife will refuse to forgive him and file for divorce.
"Liberty is not making this easy for Rupert, not surprisingly," a source close to the situation tells RadarOnline.com. "She is refusing to see him right now and has not spoken to him about if they have a future together or not.
"Rupert is willing to do absolutely anything and everything he can to save his marriage, he realizes this is the worst mistake of his life, and he cannot believe he was so stupid.
"The thought of losing his wife and children, who he loves more than anything in the world is killing him."
As RadarOnline.com previously reported, Stewart released a statement shortly after news broke of the affair insisting that it was a "momentary indiscretion" but, photos have surfaced showing Stewart and the married director looking cozy together back in May during an intimate dinner in Berlin and there have been several reports that the affair lasted for "months."
Ross was photographed out with her two children Sunday, pointedly not wearing a wedding ring, and the source says she is in serious turmoil as to whether she will ever be able to forgive her cheating husband.
"Liberty has told Rupert she just doesn't think she will be able to trust him again," the source says. "This affair went on right under her nose and she feels like he has made her look like a fool.
"Rupert is just hoping it will blow over soon and he can win her back, but that is looking ever increasingly unlikely."
Meanwhile, Stewart’s heartbroken ex, actor Robert Pattison, is scheduled to give his first post-split interview next Wednesday, August 15, on ABC’s Good Morning America.
