The two began dating in 2014
“Kylie insists that she is done with Tyga for good. She broke things off several weeks ago initially, then they got back together briefly but she says she is done now,” the source says.
The source adds that Jenner, 18, “is mad that Tyga used social media to comment on Blac Chyna,’s engagement.”
“They had a deal to all stay quiet, and Kylie didn’t like that Tyga decided to still comment,” says the source, who adds that rumors of infidelity on Tyga’s part also weighed on her.
“Over and over again, she feels like she can’t trust Tyga. There have been and continues to be too many lies,” says the source.
A second source is not sure this is the end for the on-again, off-again couple.
“They’ve broken up before and gotten back together, and it may happen again – they’re up and down and that’s what you get with an immature relationship,” the source says.
PEOPLE confirmed Thursday that the couple broke up after nearly two years of dating. They were most recently seen together at the Met Gala on May 2.
