"Rob and Kristen are on a trial separation right now. For Kristen, it's all or nothing. She's ready for marriage, but Rob is over the relationship. When Rob returns, they'll assess their relationship, but he doesn't want to get back together, because she's co-dependent," a source said.

"Basically, I'm an American whose brothers are in a criminal gang in Australia. Guy Pearce's character kidnaps me to try and find my brother. Other than that, it's really complicated. But it's cool. It's really fun."
The couple's relationship was put in jeopardy when Kristen Stewart's cheating scandal broke out summer of last year. Kristen had a scandalous affair with her "Snow White and the Huntsman" director Rupert Sanders. However, Robert Pattinson graciously forgave his girlfriend.
