Kristen Stewart is reportedly disappointed that Robert Pattinson has yet to fully forgive her for the publicized affair with "Snow White & Huntsman" director Rupert Sanders last July. According to a source, Pattinson, 26, is still undecided about moving forward completely from the betrayal despite all the time they have spent together since their reconciliation in September. "Rob and Kristen are at a crossroads right now as to whether he finally accepts they are back together or not," the source told Radar Online. "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."
