Camille Grammer may be signing off from the " Real Housewives of Beverly Hills" but she isn't ending her very public feud with ex-husband, Kelsey Grammer.

The 43-year-old former dancer and model appeared on " Good Morning America" today to discuss why she won't be returning for a third season of the hit Bravo reality TV show but, instead, took time to look back at how her run with the show began.

"The first season was horrible because they were filming me during the worst year of my whole life.  My whole life was falling apart," she said.  "My husband left me.  He was having an affair with another woman in New York City while I was filming a reality show.  It doesn't get worse than that."

The 13-year marriage between Grammer and the former "Frasier" star Kelsey Grammer disintegrated on camera during the show's first season in 2010.  As Kelsey went to New York to star in a Broadway show, Grammer stayed in California to care for the couple's two children, now 7-year-old son, Jude, and 10-year-old daughter, Mason.

During that time, as cameras were rolling, Grammer learned that Kelsey, 56, was seeing 30-year-old British flight attendant Kayte Walsh, whom he later married.  He has claimed that he and Camille's marriage was over before the reality show began and called his agreement to participate in the show his parting "gift" to her.

"Yes, thank you, Kelsey, for the gift of humiliation for the first season," Grammer said today on "GMA."

"I don't believe that.  I don't," she said of her ex's claims that their marriage was over.  "Maybe for him but I didn't know about that."

Grammer has now moved on to a new love in her life, her boyfriend of eight months Dimitri Charalambopoulos.

"He's a really good guy," she said.  "He's a sweetheart."

Despite rumors that she was fired from the show, Grammer says it was her decision to leave the show and castmates Kim and Kyle Richards, Taylor Armstrong, Lisa Vanderpump and Adrienne Maloof behind.

"I gave them [Bravo producers] a list of things I didn't want to shoot, my children and my relationship with my boyfriend, because I believe that certain things should remain private and sacred," she said.  "From that they came back with an offer but it was not one that I was comfortable with after being on the show two years as a main housewife."

"They just couldn't have it," she said of Bravo's desires to film her private life.  "Being in a new relationship is exciting and difficult and there's some things you really want to remain secret.  And I don't think my ex would have signed off on it and I didn't feel comfortable exposing my kids."

The experience of going through an affair, divorce and custody battle on national TV has not entirely deterred Grammer from a future back in the spotlight.

"All things are possible," she said of the chance she could return to reality TV.  "I enjoyed my experience with the franchise and we're still talking."
