According to a source, Pattinson has called an end to their romance as he “grew tired” by the fact they had been “drifting apart”, reports thesun.co.uk.
“In recent months they have really started to drift apart and have been spending less and less time together,” the source said.
“Rob is tired of it, has called off their engagement and told friends they have split. With so much history between them, though, there are still strong feelings there.
“It’s a difficult situation but things have become tough between them for some time and they both know they were no longer working as a couple,” the source added.
