Kristen Stewart "frustrated" that Robert Pattinson is "playing hard to get"
The Twilight co-stars briefly split this summer after Kristen confessed to cheating on Rob with Snow White And The Huntsman director Rupert Sanders, 41.
Rob, 26, eventually took Kristen back and the pair happily posed together at numerous Twilight premieres last month - but it seems all is not well behind the scenes.
It's reported that Rob's still unsure about the relationship and is therefore "playing hard to get" - but Kristen's frustratingly doing all she can to convince him they can make it work.
A source claimed to RadarOnline.com: “Rob and Kristen are at a crossroads right now as to whether he finally accepts they are back together or not.
“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 world was in shock in July when photos emerged of Kristen kissing married 41-year-old Rupert.
She quickly issued an apology as Rob hid away from the spotlight, with reports his loved ones were furious with the US star for betraying the English actor after years together.
Especially incensed were Rob's sisters, Lizzy and Victoria, who are very close to their brother.
But since her reunion with Rob, Kristen has reportedly tried to make things right with the Pattinson family.
The source continued: “She knows his sisters were particularly vocal about their disapproval of Rob taking her back after the affair, so Kristin braved the storm and grovelled to them.
“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."
