Although actress Kristen Stewart has apologised for cheating on her boyfriend actor Robert Pattinson, she is reportedly upset about having to suffer the wrath alone.
Stewart, 22, had an affair with director Rupert Sanders, even though she was in a three-year relationship with the actor.
"Kristen can't believe the public isn't painting Rupert Sanders as the bad guy. She's grousing that he's 19 years her senior and was in a position of power over her ... being a director of a movie she had just shot and presumably someone she was going to work with again," tmz.com quoted a source as saying.
The actress is also upset about being called a cheater. Although she accepts her actions were wrong, but believes that Sanders is at a more culpable situation as he is married and has two children.
Stewart met the director on the sets of movie, "Snow White And Huntsman".
