Rob accepted Kristen's offer to speak in person,after spending ages talking on the phone a few days ago.
What made him change his mind? According to a close friend of his who talked to Look magazine, he feels bad for Kristen and he's ready to talk to her face to face.
He knows that Kristen came off as the major villain in this story, so he's going to talk to her face to face about everything that's happened.
Remember, when the news first broke that she'd cheated on him, she tried to fix things right away by issuing an apology, but Rob didn't want to talk to her at all. He's reportedly spent the time since then ignoring her endless calls and messages.
But a month later, he's given in and they'll talk in person.
This news comes a week after Rob confirmed that he would be appearing at the Breaking Dawn: Part II premiere in Los Angeles.
