The couple—who are parents to daughter Aurelia, 4, and son Lucia, 2—are breaking up after seven years together.
"Telling my kids that baba & daddy are separating will always hurt," Richard tweeted April 17 alongside a family selfie. "We had a great run. So much love, two beautiful babies & two angel babies."
Ricard dedicated a message to Andy, whom he eloped with on New Year's Eve 2015 before they hosted a wedding ceremony in May 2018.
"You're my best friend," continued Ricard, who appeared on Survivor's season 41. "Our first family trip as just friends proved even more that we're still soulmates, just in a different way."
Andy has not yet commented publicly on the split.
Ricard and Andy first met while volunteering at a queer youth camp in 2015 and eloped that year. In 2018, Andy, moved by his transgender community, told Ricard he stopped his hormone treatments and was ready to try to have kids and carry them himself.
Andy referred to himself as a seahorse dad, since male seahorses give birth to their babies. The pair welcomed Aurelia in 2019 and Lucia in 2021.
"Prior to meeting Ricard, I had not really thought about having kids and definitely not carrying kids," Andy told E! News in March 2022. "But once I met him, it was clear I did want to have a family with him."
As for Ricard, he said he was initially closed off to the idea, but "we met and I learned so much more about my queer community and so much more about what's possible."
Since becoming a dad, the Survivor star has become in awe of his kids' blossoming personalities.
"I thought they would just mimic us, use our mannerisms and phrasing until they were older," he told E! News last year. "But [Aurelia] is going to be the person she's going to be and that's all on her. We're here to help her grow and it's really cool to see that, at such a young age, she is her own person. And Lucia's getting there. He's hilarious."
