Marriage? Haven't you guys only just got back together?
The Twilight couple briefly split this year following Kristen's revelation that she has cheated on Pattinson with 'Snow White and The Hunstman' director Rupert Sanders.
According to The Daily Star, Robert has apparently told Kristen that in order for them to officially be an item again she must be willing to fully commit to him.
A source told the paper: "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."
The source also revealed that Rob never stopped loving the actress despite her indiscretion.

They said: "Although Kristen broke Rob's heart he has realised he can't live without her. He never stopped loving her and he believes she still loves him.
"He is desperate to make it work and wants to give her another chance but not unless she proves she really wants it too."
This is not the first time that Rob has proposed marriage, with the source saying that the two had previously talked about the idea before they split.
The source revealed:"They have both talked openly about marriage before and she's been telling him for years that she doesn't want to rush into anything."
"But Kristen will do anything to get back with Rob now and one of the conditions is to discuss getting married and the future."
The two will be reunited on screen in November when the final part of the Twilight saga hits cinemas worldwide.
