(Cover) - EN Showbiz - Robert Pattinson has reportedly decided to depart from the home he shares with girlfriend Kristen Stewart.

The Twilight stars are currently experiencing turmoil in their nearly four-year relationship.

Kristen, 22, publicly revealed this week that she cheated on Robert, 26, with her Snow White and the Huntsman director Rupert Sanders, 41.

Robert packed up and left his and Kristen's Los Angeles residence and sources aren't convinced that he'll be moving back in.

"I'm not sure they'll be able to recover from this," an insider told People magazine.

"[Robert] is heartbroken and angry."

In the statement of apology Kristen released Wednesday, the actress declared Robert to be "the person I love and respect the most."

The star is rumoured to be in shambles over the way her indiscretion has impacted her beau.

"Kristen really loves Rob more than anything," a source said.

"He's all that matters to her right now."

Director Rupert shares two children with his wife model Liberty Ross.

Now it has been claimed that Kristen is eager to make amends with Liberty.

She has reportedly decided to privately ask for the British model's forgiveness by writing a personal letter. (C) Cover Media
