Pattinson moved out of the house that he shared with girlfriend Kristen Stewart following her admission that she cheated on him with married director Rupert Sanders.
"Robert has resorted to asking strangers out to keep him company. He went out for drinks with a woman staying in his hotel and he told her it was 'ridiculous' he had nobody to talk to," thesun.co.uk. quoted a friend as saying.
The 26-year-old has also been spending a lot of time alone trying to forget his relationship difficulties. "He's been spending most of his days off just playing computer games," added the friend.
After the couple moved out of their house, friends said they feared they won't be able to repair their damaged relationship. "I am not sure they'll be able to recover from this. Robert is heartbroken and angry," said the friend.
