"She is serious about taking the bar exam and becoming a lawyer, she is serious about her prison reform campaign," they said, before explaining that Kardashian has already gone to West's Wyoming ranch to "quietly" sort things out. "Meanwhile Kanye is talking about running for president and saying other crazy shit, and she's just had enough of it."
A second insider also said that while "this isn't the first time they've been talking about a split," it is now "way, way more serious."
Meanwhile, another source added that West is now "completely over" the Kardashian family's reality antics and "wants nothing to do with them," before pointing toward the way he "showed up late and left early" from Kardashian's 40th birthday event.
"He wouldn't appear in any of their Instagram shots," they said. "All he did was bring over the hologram of her father Robert Kardashian, then got out of there as fast as he could."
Kardashian and West have reportedly not decided on how to split their properties. However, the source went on to explain they'll likely battle over their shared Calabasas home as Kardashian "owns all the land and adjoining lots around the house but Kanye owns the actual house."
"Kim is trying to get Kanye to turn over the Calabasas house to her, because that's where the kids are based and growing up," they said. "That is their home."
Neither Kardashian nor West have responded to the report yet. Read Page Six's full report, here.
