The 26-year-old actor is refusing to meet her face-to-face but he is still concerned about his "Twilight" co-star, reported Femalefirst.
"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," a source said.
