Recent reports suggest that Robert Pattinson is looking to break up with Kristen Stewart for good after he returns from Australia because he still hasn't gotten over the cheating scandal. 

2012 hasn't been very good for the relationship Pattinson and Stewart. After a scandalous cheating affair, Pattinson forgave and took back Stewart. However, now reports suggest trouble between the two again. A recent report from Hollywood Life states a source told them that once Pattinson returns from Australia; he will call things off. Even though the duo is together, Pattinson cannot forget the cheating scandal.

"Rob and Kristin are on a trial separation right now. For Kristin, it's all or nothing. She's ready for marriage, but Rob is over the relationship," the source told Hollywood Life

Pattinson is currently shooting for his upcoming new film "Rover" in Australia and won't be seeing Stewart for a good two months that he'll be busy shooting for.

"When Rob returns, they'll assess their relationship, but he doesn't want to get back together," the source said. "On the other hand, Kristen wants to get back together because she's co-dependent. Rob's been shaky ever since the cheating scandal."

The report also suggests that Summit Entertainment is hoping the couple decided to remain together till the DVD/Blue ray copies of Breaking Dawn Part 2 has been released so that the sales will be pushed up.

Forbes also announced Pattinson and Stewart as the highest earning couple earning1.17 billion at the U.S. box office over the past three years from their "Twilight" series.

Contrary to breakup rumors, some tabloids have also reported that Pattinson and Stewart will be looking to tie the knot soon.
