A breakup can be shocking enough, but being told it’s over with “no warning” is another story entirely. Elon Musk‘s girlfriend Shivon Zillis revealed on X on October 2 that their romance is officially done.

The 40-year-old Neuralink executive gave a lengthy statement about their split on her ex-boyfriend’s social media platform after five years together. They also share four children: fraternal twins Strider and Azure, 4, daughter Arcadia, 2, and son Seldon, 1.

“It’s hard to go from in love to let go in a week with no warning, but that’s just how it is sometimes,” she wrote, confirming the breakup was a one-sided situation.

“I feel happy that I got to show Elon how it feels to be deeply understood, nurtured, and peacefully loved with stability and gentleness,” Zillis continued. “Given the tumultuous nature of his early life, his often tortured soul, and how hard he fights for humanity, I wanted him to feel the deepest and most stable form of love this world can provide.”

Zillis felt that she was a “counterbalancing place of safety, sense of calm, and love” for him, and she was going to “miss him dearly.” She also took the high road of praise, noting he made her “cup overflow with life meaning,” especially with their “four beautiful little loves.”

In the end, she hopes to “be great friends and co-parents” with Musk even though she is “hurting.” While Zillis’ message was quite clear that she was still in love with him, she also included a screenshot of their last text on September 24 where they exchanged “love yous.”

Musk is the father of 14 children, including one who died as an infant, with four different women: Justine Musk, Grimes, Ashley St. Clair, and Zillis. The birth of Zillis’ child with Musk also overlapped wth the birth of his son, Romulus, who was born in September 2024, with St. Clair.

The tech billionaire’s relationships with women have always been complicated, and that fact is about to come to light in Alex Gibney’s documentary, Musk. His ex-wife, Justine, appeared in the film and shared that during the first dance as husband and wife, he whispered to her, “I am the alpha in this relationship.”

Justine shared in the documentary, “I learned the term ‘gaslighting’ through my relationship with Elon. He was constantly remarking on the ways he found me lacking,” she said while noting how “insignificant” she felt while married to him.

And she also had a chilling warning for anyone who wants to have children with the SpaceX founder. He considers women to be “breeders” and that “the breeders are interchangeable.”

Musk’s life behind closed doors is becoming very public, thanks to Zillis’ post and Gibney’s upcoming documentary. It’s a side of him that he probably didn’t want revealed.
