Pattinson worried for Stewart
"Robert is still deciding what to do. He's been talking to Kristen briefly on the phone everyday, but they haven't met," femalefirst quoted a source as saying.
"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," the source added.
Stewart is keen on seeing Pattinson.
"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," said the source.
Pattinson's friend Tom Sturridge wants him to come stay with him and girlfriend Sienna Miller in London, to get a breather from the situation.
"Tom and Sienna have really been there for him. They think he needs to escape Hollywood right now," said the source.
