Kim Kardashian and Pete Davidson have called it quits.

The two have decided to remain friends after splitting up this week, a source told E! News. Kim and Pete have a lot of respect for one another, but found the long distance and their demanding schedules "made it really difficult to maintain a relationship," the source added.

"Pete is 28 and Kim is 41 — they are just in very different places at the moment. Pete is totally spontaneous and impulsive and wants her to fly to New York, or wherever he is on a moment’s notice. But Kim has four kids and it isn’t that easy. She needs to focus on the kids," an insider told Page Six, adding that Kim is "totally exhausted by this relationship and other things going on in her life."

The ex-SNL star has been spending time in Australia filming a movie while the SKIMS founder works to co-parent with ex-husband Kanye West.

An insider said Kim's relationship with Kanye has also put a strain on her relationship with Pete. "When Kim is with someone else, Kanye can cause problems with the kids. He tries to divide and conquer. He can’t help it. Kim is a really dedicated mother, and her kids will always come first. She wants and needs harmony at home and in her life," the insider told Page Six.

Kim and Pete confirmed they were dating in November. The two have made their relationship public online and offline, including at the Met Gala and on The Kardashians, where he's slated to appear in the show's second season. Pete has also recently spotted at The Grove mall in Los Angeles with Saint, Kim's eldest son. As you'll recall, Pete has gotten several tattoos during his relationship with Kim, the most recent one being last month.

This is a developing story.
