Blac Chyna and Rob Kardashian split

Rob Kardashian and Blac Chyna have split, ending their year long engagement. According to PEOPLE, the split was fueled by insecurities in the relationship.

They split a while ago. The wedding plans are off,” a source close to Kardashian told PEOPLE. “They are both trying to be mature about it. It was less dramatic this time.”

Although the couple attempted to make their relationship work, the insider tells PEOPLE that Chyna became frustrated with Kardashian over time.

Chyna is super fed up with Rob and thinks he is way too emotional and depressed. She thinks he has terrible issues,“He is always battling his own insecurities and is unstable. It’s a major turn-off to her, and she thinks it’s incredibly unhealthy for the baby and their family.”

Just last week, the mother of two was seen out to lunch with Jamel Davenport, a guy she was spotted getting close to during a Super Bowl party at Estrella’s MA Theater in West Hollywood last weekend, without her engagement ring.

“They’re living separately and she’s keeping Rob at arm’s length, both from the baby and from her,” the insider adds.
