Los Angeles, Feb 17 (IANS): Reality TV personality Rob Kardashian and model Blac Chyna have split again following her cheating scandal last year.

According to a source, Rob decided to end his relationship with Chyna as she "often disappears". 

"Rob thinks it's the right decision," the source told usmagazine.com.

"Chyna has disappeared for days at a time without communicating or providing any updates. This won't end well."

Another source said Rob and Chyna have been at odds since their initial split around the Christmas holiday. 

At the time, Chyna took all of her belongings and left with their daughter Dream. 

"(It's the same) with her yelling and screaming about how his family doesn't like or support her, and his insecurities," said the source. 

According to one of the sources, Rob and Blac are now living separately. The younger brother of Kim Kardashian has been staying at the Calabasas home bought by his mother Kris Jenner, while Chyna moved back into her home.
