Rob was planning to propose

Robert Pattinson was “weeks away” from proposing to Kristen Stewart before finding out she had cheated on him.

Pattinson was reportedly planning to pop the question to his Twilight Saga co-star in the spring, and had even bought a home for them to share before news of her fling with her Snow White and the Huntsman director Rupert Sanders broke.

A source told the Sunday Mirror: “Robert hoped to marry Kristen and was making preparations to spring a proposal before she admitted cheating. He had bought the house in Los Angeles to be their home and saw them staying there for a long time.”

The insider claimed that the two have not spoken since news of Stewart’s fling with 41-year-old Sanders broke and have only exchanged “heated” text messages.

Over the weekend, two removal vans were spotted at the couple’s home, although it is not clear whose belongings were being removed.

After pictures of Stewart and Sanders kissing were published by Us Weekly, both parties released public apologies for their actions. Stewart issued an apology to Pattinson for what she described as a “momentary indiscretion” and declared her love for him. Sanders has also apologised “profusely” to his model-and-actress wife Liberty Ross – who played Stewart’s mother in Snow White and the Huntsman – in the hope that he can save his marriage.

A friend explained: “Liberty is hurting. But she’s realistic. Things happen and marriage isn’t easy – she just hates the fact her name’s been dragged into all of this. Rupert has apologised profusely and she has accepted his apology. She hopes things get back on track – after all, they have kids together.”

Pattinson now reportedly wants to have a “man-to-man” chat with Sanders to find out “exactly what happened” between 22-year-old Stewart and the director.

A source said: “Rob wants to have a man to man chat with Rupert to find out exactly what happened between him and Kristen.

“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.”

Despite their personal lives, Pattinson and Stewart are contractually obliged to be pictured side by side on the red carpet at the premiere of their final Twilight Saga movie together, The Twilight Saga: Breaking Dawn – Part 2, which is scheduled for release in November this year.
