Despite Stewart's public apology and declaration of love for Pattinson, he has moved out of their mansion here. He is struggling to get to grips with the situation.

"Robert was indifferent to her statement. Kristen wrote it and she is desperately trying to make up for the fling by expressing her love for him," added the source.u00a0"It's incredible not only would Kristen do this, but to do so in public beggars belief. Robert needs to get his head round it.

"It was like a bolt out of the blue. He was on his own when he got a call from his agent and there was stunned silence as he tried to take it all in," said the source.
