LOS ANGELES: Actor Robert Pattinson reportedly wants to marry actress Kristen Stewart and that is the only way he agrees to reconcile with her.

Pattinson, 26, was left heartbroken when Stewart cheated on him by having an affair with director Rupert Sanders. The actress later pleaded guilty for her actions and Pattinson in return demanded a serious commitment from her.

“Rob told Kristen the only way he can forgive her affair is if she truly commits to him. Rob has been keen to marry Kristen for quite a while and he doesn’t want to get back with her unless he knows she means it for life too,” dailystar.co.uk quoted a source as saying.

“He is desperate to make it work and wants to give her another chance but not unless she proves she really wants it too,” the source added.

Pattinson and Stewart met during the filming of “Twilight” in 2008 and have been together ever since. They will be seen together again in “Breaking Dawn 2”, the last movie of the “Twilight” franchise.
