Yolanda and David Foster announced their plans to divorce this past week, but "The Real Housewives of Beverly Hills" star still sees their relationship as a "beautiful love story" that she'll "treasure forever."
Gigi, Bella and Anwar Hadid's mother called into "Watch What Happens Live"on Tuesday night and spoke about ending things with David, and revealed how her battle with Lyme disease affected their four-year marriage.
"Unfortunately it was not strong enough to withstand the circumstances that came our way," Yolanda told host Andy Cohen. "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."
The 51-year-old reality star does not blame anyone for the breakup. "The truth is that we both worked through the difficult time through the best of our ability," she said. "So rather than judging what went wrong, I pick to honor the great times that we shared in the last nine years. There were a wealth of good times."

Yolanda also gave an update on her health. "I am much better since the last time I saw you," she told Andy. "I have about 60 percent better brain function than I did in the last year. I can still only live and plan one day at a time. The exciting thing is watching the ["RHOBH"] episodes and inspiring me, and I could see the progress that I have made. I am excited and grateful for that. I will continue to fight for a full recovery."
ET also spoke with Yolanda about her recent split from David at the "RHOBH" premiere party. While she is focused on keeping her head up, the reality star admitted that it's been tough.
"I keep going, one foot in front of the other," she said. "Obviously, this is a difficult time and I'm heartbroken, but [I'm] grateful to have my job and be dressed and up out of the bed."
