Robert Pattinson: “Why do people cheat?”

Bad news for Kristen Stewart – Robert Pattinson is clearly against cheating.

Kristen has publicly apologised for cheating on Rob with her Snow White and the Huntsman director Rupert Sanders, who is 19 years older than her and married with two kids, but is it going to be enough?

Already, the internet is being flooded with quotes from Rob on the subject of cheating.

“There’s a thing I’ve never got, that is, why do people cheat?” he said in an interview with Italy’s Vanity Fair back in April 2012.

“I can understand the impulse (to cheat) but not how you can keep two relationships going at the same time for long,” he pondered.

Robert also spoke about his approach to relationships – and it doesn’t involved a third person.

“I’m not the casual-affair kind of guy,” he said. “If I choose to be with someone it’s because I really want it. When I have a relationship, I’m 100 percent into it,” he stressed.
