Kristen Stewart has had a tough time dealing with the consequences of cheating on Robert Pattinson this summer, but for his part, Rob seems to be doing better each day.

And apparently, his caring sisters believe he’d be better off without her in the long run!

DETAILS: It’s Over! Robert Pattinson Moving On From Kristen & Putting Their Pad Up For Salec

According to RadarOnline, Rob’s sisters Victoria and Lizzie have advised Robert to stay single and would kill him for going back to Kristen Stewart.

A source told the site:

“Robert’s sisters were fuming with Kristen for hurting their brother in the way she did,” a source revealed.

“Lizzy and Victoria feel terrible for heartbroken Robert, especially because of the embarrassment that was caused by the manner in which the affair was exposed.”

“They’ve told him that there’s no way he can take Kristen back after what she did to him.”

According to RadarOnline, Rob’s sisters Victoria and Lizzie have advised Robert to stay single and would kill him for going back to Kristen Stewart.

The sisters truly believe that the saying “once a cheater, always a cheater” applies to Kristen:

“It’s a case of once she’s cheated, what’s to stop her doing it again and Lizzy and Victoria are pretty unforgiving over Kristen’s actions.”

“Instead, they believe Robert should embrace singledom, throw himself into work and not consider settling down with anyone until he’s ready.”

“They will kill him if he gets back with Kristen.”

Rob has been taking all the steps possible to get Kristen out of his life, including moving out of their shared L.A. home, but only he knows if he can get her off his mind for good.

Do you think that Robert should listen to his sisters?
