Robert Pattinson (
British actor Robert Pattinson was devastated when his 'Twilight Saga' co-star and offscreen love cheated on him with married director Rupert Sanders and while he is refusing to meet her face-to-face, he is still concerned about her.

A source said: "Rob is still deciding what to do. He's been talking to Kristen briefly on the phone every day but they haven't met. He's worried about how the stress of it all is affecting her and asks how she is - but he's told her he's not ready to hear her explanation of what happened.

"He knows she's going through as much hell as he is but he's not sure he's ready to see her or forgive her. Kristen has told him she doesn't expect or deserve forgiveness, she just needs to see him to explain."

Meanwhile, Robert's friend Tom Sturridge wants the actor to come stay with him and girlfriend Sienna Miller in London.

The source added to Closer magazine: "Tom and Sienna have really been there for him. They think he needs to escape Hollywood right now."
