Kanye West 'Resigned to Reality' After Kim Kardashian's Divorce Filing: It's a 'Somber Day' Says Source

Kim Kardashian Files for Divorce from Kanye West After Almost 7 Years of Marriage

Sources told PEOPLE in January that a divorce between the stars was "inevitable"

Kimye is over.

After Kim Kardashian officially filed for divorce from Kanye West on Friday, the rap star, 43, "isn't happy" but "resigned to reality," a source close to West tells PEOPLE.

"He knew it was coming, but that doesn't make it any easier," the source says. "This is a somber day for him."

The new information comes after a source told PEOPLE that the divorce filing had been amicable, with both West and Kardashian in agreement over joint legal and physical custody.

"It's as amicable as possible, but amicable doesn't mean joyful or ideal," the West source tells PEOPLE. "It just means that they're being adults about the whole thing."

"Kanye is seeing counselors and advisors to help him through this spot. It's rough for him, and he isn't happy, but he's resigned to reality," the insider adds.

The divorce filing — and new developments — come just days after a source told PEOPLE that Kanye was "not doing well" amid the couple's split.

"He is anxious and very sad. He knows that the marriage is over, and there's nothing that can be done right now," the source said on Wednesday. "He also knows what he is losing in Kim."

The Keeping Up with the Kardashians star, 40, and the rapper started dating in 2012 and got married in May 2014. They share four children: daughters North, 7½, and Chicago, 3, and sons Saint, 5, and Psalm, who will turn 2 in May.

The split comes after a tumultuous period for the pair, who appeared to be on the brink of divorce last summer before reconnecting and spending private time together with their children.

Then, in January, multiple sources confirmed to PEOPLE that Kardashian had been working with high-profile divorce attorney Laura Wasser and planned to file for divorce from West.

"They are just not on the same page when it comes to their future as a family," one insider said. "And Kim is okay with it."
