Robert Pattinson: Why He Really Dumped Kristen Stewart 

Why Robert Pattinson Broke Up With Kristen Stewart: The Epic Fight

Rob, 27, became “consumed” by paranoia that Kristen could cheat on him again, and a source close to the actor tells  how this ended their relationship:

''It all comes down to when she cheated on him, he couldn’t let it go and would always make remarks to her saying things like, “How do I know you are there?” “How do I know you are telling the truth?” “What else have you lied about?” It just consumed him to such a point that they would have occasional banter back and forth where they weren’t nice to each other. Her cheating basically opened other doors in their relationship of what they didn’t like of each other. There conversations where more bickering then loving, and in front of friends Kristen made jokes of the incident making it look like they were above it but he was actually hurt by her bringing it up in front of friends. She got a little cocky with it and he decided to end it after it all built up to one final argument.''

How sad! Clearly, these were issues that Rob was never going to be able to deal with, considering it has been one year since Kristen’s fling with Rupert was revealed.

''They had a conversation about taking a vacation together where they started fighting about the location of where they should go and that spiraled out into the issues they had with each other and he decided it was time to move on. And as you know, he did.''

Rob is now dating actress — and former friend of Kristen’s – Riley Keough.
