Yolanda Foster knows the exact date her marriage to David Foster ended.
The 52-year-old Real Housewives of Beverly Hills star appeared on Bravo's Watch What Happens Live on Tuesday, where she candidly answered questions about her split from Foster after four years of marriage.
"I know exactly the day -- November 15," Yolanda told host Andy Cohen about the day they decided to divorce, which they publicly announced two weeks later on Dec. 1. "It was a conversation, yeah."
"Unfortunately it was not strong enough to withstand the circumstances that came our way," Yolanda said. "Chronic long term illness is extremely challenging, not only for the person that's sick, but also for the caregiver. It for sure changed the dynamic of our relationship."
"I have been by Yolanda's side over the past four years to the best of my ability as she battled with the complexities of her Lyme diagnosis," he said. "I am incredibly proud of Yolanda's determination and mission to find a cure, and how brave and open she has been by sharing her story in the hopes of changing the future for others."
