Robert Pattinson forgives Kristen Stewart after cheating on him with Rupert Sanders

Robert Pattinson and Kristen Stewart relationship was left in tatters when she was photographed cheating on him with married film director Rupert Sanders.

But Robert Pattinson and Kristen Stewart have reportedly decided to give their romance another shot.

The Twilight co-stars are said to have had a tearful heart-to-heart, with the 26-year-old actor eventually deciding to forgive his girlfriend for what he considers to be a “stupid mistake”.

A source told The Sun: “They pretty much decided they couldn’t live without each other.

“Kristen poured her heart out to Robert and told him it was a one-off and a mistake.”

Robert Pattinson and Kristen Stewart are now said to be moving into a secluded Los Angeles home together, and are hoping to rebuild their relationship.

The source added: “Rob sees it as Kristen made a really stupid mistake. After a lot of long tearful talks, they’ve worked it out.

“Rob can see how truly sorry Kristen is and has totally forgiven her. They really do love each other.”

Kristen Stewart seems to have been quietly confident about making amends with Robert Pattinson for some time.

Earlier this month, Kristen Stewart told reporters at a press conference they were “totally fine” about making potentially awkward public appearances together in November while they promote The Twilight Saga: Breaking Dawn Part 2.

Back in July, Kristen Stewart was photographed in the arms of father-of-two Rupert Sanders, breaking not only the hearts of his wife Liberty Ross and her long-term love R-Patz – but loyal fans across the globe.

In the wake of the news, both Kristen Stewart and Rupert Sanders were quick to make public statements saying that their tryst had been a mistake.

Kristen Stewart said: “This momentary indiscretion has jeopardized the most important thing in my life, the person I love and respect the most, Rob. I love him, I love him, I’m so sorry.”

While Rupert Sanders told People magazine: “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.”
