When you've been cheated on, you want to know exactly what's been going on behind your back - and Robert Pattinson is no different. According to reports, Rob has moved out of the LA home that he shares with Kristen, and now he's out, he wants answers.

According to Radar Online, a party close to the actor said "Rob wants to have a man to man chat with Rupert to find out exactly what happened between him and Kristen."

The source says that Rob is so hurt by the betrayal that he doesn't trust Kristen to tell him exactly what happened.

"Kristen has already betrayed his trust by cheating, so he can't be sure that she will tell him exactly what went on between her and Rupert. Rupert has a wife and family to save, so Rob feels like he has nothing left to lose and would be honest with him."

The source added that Rob is "blindsided", and trusted Rupert as the director of Kirsten's film - which is why he wants to find out his side of the story.

Public Relations experts are looking into the way Kristen is handling the scandal, and rating her chance for career survival.

Publicist Matt Hiltzik told The Hollywood Reporter that by making a public apology she could stay in the public's good graces.

"I think that she handled it maturely and responsibly. ... She came across (in her statement) as genuine, and it was smart and noble for her to accept responsibility so she'll be able to move to other things."
