Shannon first confirmed she and David were separating back in October in a statement to The Daily Dish. "After much thought and careful consideration, David and I have made the difficult decision to separate," she said at the time. "We remain partners in parenthood and are committed to raising our three daughters. This is not the future we envisioned, and we kindly ask for privacy, especially for our children, during this transitional time.”
The pair has documented their ups and downs during their time on RHOC, including showing viewers how they managed to come back from David's affair, later renewing their vows in 2016. However, relations between the couple were not as smooth during the last season of RHOC and she has been open about the struggles they have faced as of late. They have been married for 17 years and together the couple are parents to three daughters: Adeline, Stella, and Sophie, who have also appeared on the show.
She also addressed their split during the RHOC Season 12 reunion, as you can see in the clips above and below.
