Camille Grammer’s marriage to Kelsey Grammer fell apart as the Real Housewives of Beverly Hills’s cameras rolled over the summer while her husband was in New York, starring in Broadway’s La Cage aux Folles and beginning a relationship with flight attendant Kayte Walsh, 29.
Now the newly minted reality star is speaking out about her heartbreak.
“This is my chance to tell my story and move on,” Camille, 42, who has two children, Mason, 9, and Jude, 6, with Kelsey, 55, tells PEOPLE in an extensive interview. “Maybe it will be cathartic. Maybe this is part of my process.”
When did you find out your marriage was over?
In June I got a phone call from a mutual friend in New York who was upset by behavior of his that she’d seen. I asked, “Is he leaving me?” and she said, “Yes.” I called him but couldn’t get through, so I texted him and asked him to please call me. Nothing. An hour later, I texted him again and he wrote: “I don’t want to talk.” I wrote, “We’ve been together for 14 years; I deserve an explanation.” Finally, three hours later, he called me. He basically said, “I don’t want to be married anymore.”
