Kristen Stewart and Robert Pattinson have had one of the more publicized recent relationships in Hollywood, and now that their onscreen and offscreen romance has reportedly been extinguished, many believe the "Twilight" lovers are done for good. 
According to The Stir, it wasn't just Stewart's affair with her "Snow White and the Huntsman" director Rupert Sanders that ended their relationship; she supposedly has intense mood swings that Pattinson, 27, could no longer deal with. A source told the online news site that the two bickered over the "Cosmopolis" actor's birthday: "All this stuff came up about the cheating, about how selfish she always is, about how moody she always is," the source said. Stewart, 23, has developed a reputation for being miserable in public, so the "moody" claim isn't a hard sell. 
At first it was reported that the two might just be taking a break since Pattinson hadn't moved out of their Los Angeles home, but after he was photographed leaving in a packed pickup truck on Sunday, the speculation is getting stronger. Unless, of course, he was just doing some major spring cleaning.
Nothing with Robsten is definite, though. A source told Us Weekly they could go either way. "[Rob] is so torn," the insider said. "They could get back together." The "Twilight" duo's relationship became strained after Stewart was caught cheating on Pattinson with Sanders over last summer. She didn't deny the allegations and instead issued an apology for hurting Pattinson. 

"I'm deeply sorry for the hurt and embarrassment I've caused to those close to me and everyone this has affected," she said in a public statement July 25. "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." Stewart was recently rumored to be hanging out with Taylor Swift, who is notorious for dating and breaking up with some of Hollywood's hottest stars, according to Us Weekly
