Rob Kardashian and Blac Chyna have reportedly split up again.
Blac Chyna and Rob Kardashian
The 'Keeping Up with the Kardashians' star and the 28-year-old model, who share three-month-old daughter Dream, decided to end their engagement after failing to get their relationship back on track following their brief split in December.
A source close to Rob, 29, told Us Weekly magazine: "Rob thinks it's the right decision. Chyna has disappeared for days at a time without communicating or providing any updates. This won't end well."
Another insider said the couple, who have been living apart since their initial split before Christmas, have been struggling to get along over the past few months, adding: "[It's the same] with her yelling and screaming about how his family doesn't like or support her, and his insecurities."
The pair, who first split after they got into a bitter war of words on social media in December and rekindled their relationship when Rob publicly apologised, are still filming season two of their E! reality series 'Rob & Chyna'.
Rob's mother Kris Jenner recently hinted the duo's romance was often tumultuous.
Speaking about the pair - who got engaged after four months of dating - she explained: "You know, I think that, too, is a work in progress and they have good and bad days. It's a young relationship and they haven't known each other for that long."
