THE BUBBLE COLLECTION FEATURED IN THE NEW YORK TIMES

When they separated in 2018, Mr. Cole moved out and Mr. Perris stayed on.

“Michael said, ‘Come out here immediately,’” recalled Mr. Cole, 58.

Two years on, he’s still living there. The house is half his, after all. Still, “I wanted to be respectful to Michael and his space when I moved back in,” Mr. Cole said.

They each have their own bedroom, bathroom and workspace. The former romantic partners recently became business partners, creating a perfume company, The Bubble Collection.

“There was an emotional adjustment because I had started to acclimate to being alone,” said Mr. Perris, 60. “I was getting into a rhythm, and when Gregory moved back I had to get back to the sharing mind-set. But I was happy to have company during Covid.”
