Kristen Stewart reportedly put too much pressure on Robert Pattinson to marry her, leading to their breakup.
“Kristen wanted to go straight back to where they'd been before they first split up and pushed Rob really hard on it," a source told contactmusic.com. "She wanted the whole package- the house, the wedding and even the baby. It was all way too much for Rob to handle.”
According to reports, Stewart gave Pattinson an ultimatum.
"If Rob had got his way, they would still be dating but taking things slow," the source continued. "Rob asked for space and it sent her over the edge. She told him if he wanted a break, it would be permanent."
The decision to break up is reportedly weighing very heavily on Pattinson.
“Rob has been a mess. He's the one that ultimately pulled the plug, but that doesn't mean it's any easier on him. Rob loves Kristen and he truly wanted to spend the rest of his life with her.”
