Rob Kardashian and Blac Chyna are reportedly over for real this time.

According to multiple sources, the couple's relationship has been damaged since their last blowout fight, and now, they've decided to call off their engagement and split, Us Weekly reported.

"Rob thinks it's the right decision," a source told Us. "Chyna has disappeared for days at a time without communicating or providing any updates. This won't end well."

In late December, Kardashian, 29, publicly apologized to the mother of his child -- three-month-old Dream -- for an explosive argument, revealing that he was "embarrassed" by his actions and "seeking help to deal with his flaws." He reacted to Chyna moving out of their shared home and taking Dream with her.

Chyna, 28, vented at the time about how Kardashian was "sad and pathetic" and failed to deal with his numerous emotional and "personal issues."

And the Us sources revealed the pair's current problems are "the same." The latest breakup was over "her yelling and screaming about how his family doesn't like or support her, and his insecurities," an insider told the magazine. 

The Rob & Chyna stars are now living separately, the insider noted. Kardashian reportedly returned to his Calabasas, CA, estate his mother, Kris Jenner, purchased for $2.3 million in February 2016. Chyna, on the other hand, moved back into her own home.

Fuel was probably added to the fire when Chyna was spotted having dinner with a man named Jamel Davenport in West Hollywood last Friday, however, another source claimed their dynamic is not romantic.

Before that, Chyna was caught cozying up to a mystery man at the Super Bowl game on February 5, when the makeup artist was allegedly overheard telling a friend that while she's "still with Rob," they're not living together.

The couple has had a tumultuous relationship since getting engaged in April 2016 after a little over two months of dating. Kardashian and Chyna then announced they were expecting their first child together in May.

Rob & Chyna was renewed for a second season by E! a couple of months ago and is expected to premiere this year.
