It was just like any other morning for former celebrity couple Robert Pattinson and Kristen Stewart. Kristen was in a shower. Robert was in his playful mood. After all, it was his birthday. He reached for Kristen’s phone to take picture of something that fascinated him. Then came a message that flashed on the phone screen. It was not a birthday greeting that he would suspect he would want to see. It was nothing anywhere near close to his liking. It was a message from Kristen’s former fling, Rupert Sanders.

Robert blew his top. He stormed out of the room.

"Rob was looking at her phone on the morning of his birthday as he wanted to take a picture of something when she was in the shower. Suddenly this message flashes up and it's not what he wanted to see. He got straight up and left,” a source close to the couple revealed to celebrity blogger Perez Hilton.

He threatened to move out, for good this time. Kristen didn’t believe him. But he had reached his boiling point in the nasty summer fling.

“I don’t think Kristen took Rob seriously when he threatened to move out, but apparently he wasn’t kidding,” a source said, according to HollywoodLife.com.

Like in any romance film sequence, the angry boy leaves, collected his stuff, put them all at the back of his red pick up truck and drove away. Rob was serious to stay as far away from Kristen as possible.

The ball was in Kristen’s court. Like she did the first time she was caught, (though not inside the four corners of their L.A. lovenest, but through a series of devastatiing pictures by a celebrity magazine ) Kristen pleaded her case. She reasoned out that it was an innocent exchange between a former Summer fling. For all we know, Kristen must have been ignoring the messages Rupert was sending her. Kristen begged for Rob to come back. But they fell on deaf ears. Rob was determined to leave her.

He left in the morning of his birthday and told Kristen not to come to the birthday party organized at his friend’s house that night.

The source claimed, “Despite Kristen’s pleas, he told her not to come to his birthday party at a friend's that night. He's extremely angry and upset. No matter how many times she calls or texts, friends say he's had enough. After everything that happened and the hurt she caused, he’s furious she’d be back in touch with him, even if she is saying it’s completely innocent."

Kristen apparently didn’t learn her lessons. She could have ditched the number to avoid Rupert, said Perez Hilton. HollywoodLife noted, (and rightfully, so): “Fool me once, shame on you. Fool me twice, shame on me.”
