With the recent news of Tyga & Kylie Jenner's breakup, comes the rumors that Rob Kardashian and Blac Chyna's relationship was a contributing factor. A source told PEOPLE,
"It shook up Kylie and Tyga's relationship. It was definitely uncomfortable and there were plenty of hurt feelings on Kylie's part. "
Apparently Kylie was upset when Tyga sent congratulatory social media posts to his ex Chyna after the announcement of her engagement.
According to another source,
"The drama really started to get to Kylie. She couldn't get it off her mind. She almost felt like she was in an incestuous relationship."
Allegedly Kylie wanted to drop the situation so she could move on with her life and not carry the emotional baggage that came with the situation. Apparently Tyga & Kylie had other problems before #BlacRob started dating, and the entire situation just became too much.
