Three's a crowd no more in Eddie Cibrian's life.
Glanville, 43, revealed the pair have made peace and are embracing being a "modern family," in a new interview on Sirius XM's Conversations with Maria Menounos.
"We have to be a unit, three of us," said Glanville, adding that the trio decided to prioritize her and Cibrian's children following "moments of not putting the kids first and not being proper adults."
"I think that I've acted like a child enough during the seven years," continued the Real Housewives of Beverly Hills star. "As the kids are getting older – something did happen with one of them, and I don't really want to go into it, but it made the three of us, Eddie, LeAnn and myself, realize we have to be together on this.

"We have to stick together in order to keep these little boys in line and to keep them from not manipulating us against each other, and we need to be together for them."
Glanville filed for divorce from Cibrian in 2009, amid revelations that the hunky CSI: Miami actor was romancing country singer Rimes
The pair had been married since 2001 and had two sons together: Jake Austin, 9, and Mason Edward, 13.
Rimes was also married, to Dean Sheremet, when she met Cibrian. As her romance with Cibrian deepened, she was frequently labeled a "husband stealer."
Over the years, Rimes and Glanville have publicly feuded over social media and via interviews, but Glanville says they now spend the children's birthdays together.
"I think that LeAnn finally realizes that I don't want your man," she continued in the interview. "That's all done, but we can all still get along and be friends, and so we are."
Now that she has made peace with her former foe, Glanville can concentrate on her own love life -- and naturally she's doing it via reality television.
The dating veteran stars in the E! series Famously Single, which aims to help her and fellow Hollywood daters find love.
"I know for me, I [have] a lot of trust issues with men," Glanville told ET in an exclusive interview. "At least I recognize it more now."
