Robert, 26, has been playing hard to get with Kristen, 22, since rekindling their romance and a close source says the actress is starting to get fed up because she feels that she's been putting in all the effort to make it work.
The Twilight Saga: Breaking Dawn – Part 2 beauty believes she’s been punished enough for her affair with her married Snow White and the Huntsman director Rupert Sanders, the source says -- and thinks Robert now has to get over it otherwise the romance is destined for failure.
“Rob and Kristen are at a crossroads right now as to whether he finally accepts they are back together or not,” the source tells RadarOnline.com.
“Kristen has been trying so hard to win Rob back, she’s been hanging out with his friends and she even went to London to make a good impression with Rob’s family over the Thanksgiving holiday.
“The problem is, Rob is still dithering on what to do. I think Kristen is now at the stage where she feels it is time for him to get over her affair or perhaps move on,” the source reveals.
Meanwhile, as RadarOnline.com previously reported, Kristen has signed up for the sequel to Snow White and the Huntsman – but Rupert, 41, has dropped out.
“The script has already been written and production will begin late next year,” a source previously told RadarOnline.com.
“However, Rupert Sanders definitely won't be a part of the project. Rupert didn't want to be a part of it to begin with because he is desperately still trying to save his marriage. The search is still on for a new director.”
