A source said: "John asked Jen if they could go back to seeing each other exclusively. The call came as a massive surprise and of course Jen is delighted with John's announcement - who wouldn't be?" The 31-year-old star has reportedly promised to give the relationship his 'best shot' if she agrees to take him back.
The source explained to Britain's Look magazine: "John suggested that if all is going well with them in six months, then they can begin discussing marriage and building a life together. Jen was floored! John always seemed so anti-commitment before. But now he's begging Jen for another chance and he''s promising to give the relationship his best shot."
"Despite his big plans, John suggested they don't rush into moving in together. She'll keep her house in Beverly Hills, while John will continue to live in Pacific Palisades. I think it's just because he wants to move slowly and avoid mistakes they made previously."
Aniston was most recently linked to Gerard Butler, who she stars alongside in The Bounty, and Bradley Cooper.
