Pattinson and Stewart met on the set of "Twilight" in 2008, playing it cool by refusing to acknowledge their relationship publicly right up until news of Stewart's infidelity broke, putting the future of "Robsten" very much in question.
Pattinson reportedly moved out of the house the two planned to share in Los Angeles and was reportedly poised to ask Stewart to marry him when the scandal broke, with USMagazine getting the scoop by publishing photos of Stewart and Sanders embracing and frolicking in a park in Los Angeles in July.
Stewart (22 years old) met the much older Sanders (41 years old) when he directed her in "Snow White and the Hunstman", the latest film of Stewart's to hit the big screen. After the news broke Stewart issued the below public apology to Pattinson, which was ironically the first time she officially admitted they were a couple:
“I am deeply sorry for the hurt and embarrassment I’ve caused to those close to me and everyone this has affected. This momentary indiscretion has jeopardized the most important thing in my life, the person I love and respect the most, Rob. I love him, I love him, I’m so sorry.”
Sanders, who is married with two young children, issued his own apology, claiming to be "utterly distraught" about the pain he may have caused his family. Later reports would surface that would point to the affair going on for months, and that Sanders had persistently pursued Stewart and initiated the relationship.
Sources close to Pattinson and Stewart say that the two haven't spoker since the news broke, exchanging text messages but nothing more. Potentially rubbing salt into Pattinson's wounds is the fact that he reportedly bought the home in Los Angeles for the two to live in, with plans to propose in the near future -- possibly as soon as days before the photos were leaked that made Stewart's indiscretions public knowledge.
