Washington, October 29 Kristen Stewart has parted ways with 'Twilight' co-star/alleged boyfriend Robert Pattinson, as he was too serious about their relationship and wanted to get married, sources say.

The actor was apparently pressurizing her to take their love to the next level and was even stopping her from spending time with friends and family.

"Robert was talking marriage but she told him they needed a break," Contactmusic quoted a source as telling America's OK! Magazine.

The two also had different opinions about settling in a particular place.

The insider said: "Now 'The Twilight Saga: Eclipse' has finished filming, there's been a lot of tension about the logistics of their relationship as Robert wants to go back to the UK, while Kristen prefers to stay in Los Angeles."

However, the alleged couple was earlier sharing a suite costing 850 dollars a night at Sheraton Wall Centre Hotel in Vancouver, anada. (ANI)
