Robert Pattinson and Kristen Stewart have kept guessing their millions of fans and thousands of media outlets online as to when the British hunk will fly back to LA from Australia and be with sweetheart, Kristen Stewart.

While the filming of The Rover has officially wrapped up filming on March 16 as earlier scheduled by the film’s producers at Porchlight Films, the actor has reportedly been planning on staying Down Under. And yes, away from Kristen.

But the reasons for the actor to stay in Australia a little longer are all about Kristen. That is, according to the source who talked to RadarOnline.com. Here are the top reasons why Robert would choose to stay in Australia and not fly back to the States and be at the LA home he shared with Kristen.

1. To forget all his love troubles
The unnamed source quoted by RadarOnline.com pointed out that the location shoot for The Rover is ideal for him to go around the area and relax, allowing him to set aside the “relationship troubles” he may be in with his on-and-off girlfriend, Kristen Stewart.

“The set really is in the middle of nowhere, a good drive from Adelaide, so it's been the ideal setting for him to forget all his troubles and bury himself in his work,” the source said.

The two has been separated for months since Robert flew to Australia in mid-January. The actor began filming on January 31 and reportedly wrapped filming for The Rover on March 16.

2. To spend more time with The Rover production team
All work and no play makes is indeed unhealthy. And Robert is not planning on leaving Australia without spending quality time with the crew.

In an earlier statement by the film officials of The Rover, they asserted that the success of the film would not have been possible without the local crew.

“We certainly couldn’t have done it without everyone’s assistance, and the hospitality shown to us has been invaluable. Everyone working with us has been fantastic to deal with and our locals on the crew have been wonderful and generous with the vital local knowledge,” Liz Watts, producer of The Rover and the film director, David Michod were quoted as saying in a separate report by IBTimes-AU.

Robert is reportedly spending time to express his thanks for the assistance extended to the whole Rover team. But the source who talked to RadarOnline.com claimed this is his way to re-evaluate his relationship with Kristen.

'After filming, Robert's been keen to socialise with the cast and crew and loves being in the outback, away from city life. It's the peace and quiet he has needed since his relationship woes with Kristen, and the perfect way to re-evaluate things,” the source was quoted as telling RadarOnline.

3. He is just being “nervous”
Robert Pattinson is reportedly nervous seeing Kristen after weeks of filming in Australia. This stems from the “frosty circumstances” that he had his back on when he left for work out of States. The Cosmopolis star is uncertain of his next move, said the source.

“But, with just short of three weeks left of filming, Robert's beginning to get nervous about returning to LA and Kristen. He left in frosty circumstances and needs to make a decision on what to do next,” the source said.

4. He knows that Kristen is in good hands and there’s no rush home.
Kristen has been seen with his friends in the last two months: with Marcus Foster in two occasions in February and with Robert Taylor also in two occasions in February and March. While reports that Kristen may not be able to cope loneliness without Robert, the actor

While Rob has been working down under, 22-year-old Kristen - who cheated on him with married director Rupert Saunders last year - has been spending time with her friend and 'Twilight' co-star Taylor Lautner in a hope the hunk will have advice on how she can win Rob back for good.

The source claimed however that Kristen is using Taylor as a sounding board for her heartaches following Robert’s absence.

“Kristen has been spending a lot of time with Taylor of late because she's been using him as a sounding board for her relationship with Robert,” the unnamed insider was quoted as saying by RadarOnline.

Either that or ….

5. Robert (and Kristen) just want to keep their millions of followers guessing.
Twilight author reiterated that both Robert and Kristen love privacy, in an interview where she noted blaming herself for all the troubles the celebrity couple has had for years. This love for privacy however may result in fans kept guessing on what they are really up to and the real score of the Robsten Romance.

The pair’s love for privacy is what makes it all worst when Meyer underscored that Robert and Kristen "don't enjoy the parts [of fame] that other people would. And I totally get that, because it would not be my thing either."

Robert and Kristen remain mum on the status of their relationship. While they were reportedly asked to keep any love troubles early this month for the DVD release of the final Twilight installment, the couple has not come forward to make a stand on the Robsten Romance.
