A source said: "The girls literally thought Rob was going to die. They feel like Chyna saved him."
Rob's family weren't thrilled about the relationship at first and in new episodes of Keeping Up With the Kardashians, Khloe and Kim are seen raging over their secret engagement.
Blac has a three-year-old son with rapper Tyga, the former boyfriend of Kylie Jenner.
In scenes aired on Sunday night's episode of the show,Khloe said: "He proposed in front of her whole family. That's so f***ed up. Rob is such a p***y.
"I'm not going to cover for him anymore. What am I covering for him anymore for?"
Kim added: "I don't care if he tells me, I truly couldn't care less."
However, Kourtney was more sympathetic to Rob, telling her sisters: "Maybe he thinks that you guys are judgmental because clearly you are ... That's exactly why he didn't tell you, because you're a b***h [Kim]."
Before adding to camera: "I think that Rob has his happy life with Chyna.
"But I just hope that it gets to the place where he wants to hang out with his family again."
The source added all the drama is now water under the bridge, and the family have now welcomed Blac with open arms.
They said: "Khloé had the most issues with the relationship. She found Chyna in her kitchen [when she started dating Rob] and didn't know what was going on. She felt very disrespected.
"The [Kardashian sisters] have gotten over their issues with Chyna now. They've welcomed her in."
