Kardashian, who is currently studying to become a lawyer amid juggling other projects such as her Skims clothing line, is "trying to stay strong and move on with her life," the insider added.
The development comes just weeks after a source close to the celebrity couple claimed to People magazine the pair "completely" stopped going to marriage counseling.
Kardashian has yet to file for divorce but at the start of 2021 fans were stunned to learn a split between the two is "imminent." She has reportedly hired Laura Wasse, a well-known divorce attorney in Hollywood who frequently oversees starry splits.
People's insider claimed the 43-year-old rapper was set to begin discussions with divorce lawyers.
Reps for Kardashian and West did not respond to Fox News’ multiple requests for comment.
West, a Grammy-winning musician, has been noticeably silent regarding the divorce rumors, was last active on social media during the 2020 presidential election. Meanwhile, the 40-year-old "Keeping Up with the Kardashians" star recently crossed a milestone of having 200 million followers on Instagram.
Kardashian has remained in Los Angeles with the couple’s four children, while West allegedly prefers to live at his Wyoming ranch, Page Six previously reported.
Trouble in paradise between the two was first reported over the summer when West announced his candidacy for president in the 2020 election.
During what Kardashian later implied was an episode brought on by his bipolar disorder, West brought up the possibility of divorcing his wife at a campaign event while claiming they considered aborting their first child.
"Even if my wife wants to divorce me after this speech, she brought North into the world even when I didn’t want to," West told a crowd while crying, according to People magazine.
In a since-deleted tweet, the "Power" rapper also claimed that he’d been "trying" to divorce Kardashian ever since she attended a prison reform event with Meek Mill in 2018.
In the same rant, he also shaded Kardashian’s past Playboy spread and claimed that the reality star’s mother, Kris Jenner, was no longer allowed to see his children.
In July, it was reported that the couple had been considering divorce for weeks and that Kardashian and her famous family were "shielding" her children from their father’s public outbursts. Later that month, the stars were spotted having an emotional conversation in Wyoming.
Things seemed to be better between the two as Kardashian showed support for her husband at one of his Sunday Service events in August and was also seen laughing with West in a family video that same month.
Last month, however, it seems things may have taken a turn for the worse as reports surfaced that the two were leading "separate lives" and had been spending "a lot of time apart."
The marriage is West’s first and Kardashian’s third. She was previously married to Damon Thomas from 2000 to 2004 and to basketball pro Kris Humphries from 2011 to 2013, though she filed for divorce after just 72 days of marriage.
Kardashian and West share four children: North, 7, Saint, 5, Chicago, 3, and Psalm, 1.
