Still of Pattinson and Stewart during wedding
scene in "Twilight"
Heartbroken and humiliated ‘Twilight’ star Robert Pattinson was reportedly set to propose to girlfriend and ‘Twilight’ costar Kristen Stewart before it was revealed that the actress had an affair with her ‘Snow White and the Huntsman’ director Rupert Sanders.

The Daily Mail reports that a source revealed that Pattinson was preparing to spend the rest of his life with Kristen Stewart.

“'He had bought the house in Los Angeles to be their home and saw them staying there for a long time,” the source said.

That all came to a screeching halt when Stewart’s infidelities came to light. Perhaps making matters even worse, Rupert Sanders is a married father of two, and someone whom Pattinson trusted professionally.

“Now Rob is angry – he’s left the mansion and not spoken to her since. They have exchanged heated text messages only.” Pattinson reportedly wants to have a “man to man” chat with Sanders regarding the drama.

Despite Stewart releasing a statement saying that she was “so, so sorry” about her “momentary indiscretion,” Pattinson reportedly still doesn’t know what to believe.

“Kristen has already betrayed his trust by cheating, so he can't be sure that she will tell him exactly what went on between her and Rupert. Rupert has a wife and a family to save, so Rob feels like he has nothing left to lose and would be honest with him.”

“He still can’t fathom why she cheated. Kristen is begging for another chance. Robert is undecided.”
