After more than four years together, the pair confirmed the split in separate statements posted to Instagram on Monday.
"After 4+ years Chrishell and I are no longer together," G Flip wrote.
"I will always love her, we will always share a special connection and I cherish our memories together deeply."
The Melbourne-born singer and drummer said they were struggling with the separation and asked fans to respect their privacy.
"My head & heart are feeling very heavy right now and I'm not able to talk but I want to thank you all for your support and appreciate you respecting our privacy at this difficult time."
Stause shared the news in an emotional video, saying the pair had agreed to approach their public separation with "love and respect".
"That's not hard for me because I am in love with this person," she said.
The reality television star said she doesn't "have all the information or the reasons" for their split, but said that she's sure with time, "I will heal and everything will be fine".â�
"Definitely never doing this again, but I felt like you guys deserved a little bit more than a cold written statement because you have been so supportive and so loving," she said.
Stause said she felt like "a little bit of a failure" and needed the time to "heal" and work through the separation.
Despite the heartbreak, Stause reflected fondly on their time together.
"I had an amazing over four years with G. Maybe that's not a miss, you know. Maybe it's just coming to terms with it being a different ending than you had imagined," she said.
"I will always love G, and I don't ever really see that changing. This sucks, but everyone deserves to be happy and I wish that for both of us."
The former couple first met at a Halloween party, hosted by fellow Australian star Tones and I in 2021.
That same year, Stause appeared in the musician's music video for Get Me Outta Here.
They went public with their relationship in May 2022, when Stause confirmed their romance during a reunion episode of Netflix's Selling Sunset.
The couple married in a private Las Vegas ceremony in May 2023, later celebrating with family and friends, including in Australia.
They continued to mark their relationship with further wedding celebrations, including a medieval-themed ceremony in Los Angeles in July 2025.
