Blac Chyna and Rob Kardashian

*The KUWTK family have yet to publicly comment on brother Rob Kardashian’s engagement to former stripper Blac Chyna. Sources say the women are not happy that Rob pulled this stunt, with Khloe saying that she feels betrayed by her brother, so she refuses to even acknowledge his engagement.

“Ever since Khloé found out that Rob is dating Blac Chyna, she felt betrayed,” the source says. “This feeling has never changed. After finding out about the engagement, she is furious at the lack of respect.”

Rob, 29, proposed to Blac Chyna, 27, last week – with the news taking the family by surprise, says the source.

“She can’t believe Rob didn’t tell the family in advance. She thinks Rob is causing drama on purpose and wants them [his family] to be arguing,” says the source.

So far, Rob’s sisters and mother Kris Jenner have remained silent concerning the engagement.

“Khloé plans on ignoring the news. She is not going to send Rob any well wishes. She is not happy about the engagement, and is not going to pretend that she is,” the source adds.

A source previously told PEOPLE the Kardashian-Jenner clan was concerned about Rob’s relationship with Blac Chyna.

“There has been a fear that Blac Chyna is manipulating the situation with Rob,” said the source. “That he is getting himself into a situation that is not ideal for him. Blac Chyna has been great as kind of a rebound. As someone that got Rob out of a dark place, that helped him get motivated and healthy again. Let’s just be honest, no one is really hoping for a marriage to happen.”

Do you think Rob and Chyna’s relationship is genuine or a cleverly crafted PR stunt? One that is possibly orchestrated by Kris Jenner in order to establish a storyline for next season of KUWTK?
