Carlton and Diamond's relationship was the first one to end. After Carlton revealed that he had dated both men and women in the past, the couple had some serious problems and, ultimately, a devastating onscreen fight ended with them breaking up leaving the show. Although they're obviously not together anymore, Diamond did tell "Entertainment Weekly" that they were friends before the reunion episode, which Carlton didn't attend.
"Carlton and I were able to establish a friendship after the show. But it took a very long time for myself. Carlton reached out to me on several occasions. I wasn't ready. I had to put that behind me and remind myself that he was a good person despite what happened on the show and don't hold grudges. I finally reached back out to him after he made several attempts to reach out to me, and it started out as small talk, like happy birthday or happy new year or hope all is well. He did apologise. So I finally reached back out to him, and we've had conversations," Diamond revealed to the outlet in February 2020.
While Diamond initially expressed that the two were on good terms, by April 2020 she told TMZ that she blocked her ex on social media, saying, "The reason why I blocked Carlton was the fact that after the reunion, Carlton was being very foul-mouthed against me on all of his social media pages, and I felt that was, like wow that really shocked me. I thought we were on good terms… after that apology I never heard anything from him."
As of 2022, it appears that the two are not in contact anymore and do not follow each other on social media.
