Yolanda Foster's fans and Real Housewives of Beverly Hills castmates were shocked when she announced her divorce from husband David at the beginning of December, but the model is now revealing that the end of her marriage happened slowly in step with her Lyme's disease battle.

"We had a beautiful love story that I will treasure forever. Unfortunately it was not strong enough to withstand the circumstances that came our way," she lamented to Andy Cohen during a call-in to Watch What Happens Live.

"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," she admitted.

The Dutch beauty is trying to stay positive about the very negative situation, though!

"The truth is that we both worked through the difficult time through the best of our ability. 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," she insisted.

Her confessions come on the heels of a new report from Us Weekly that claims her music producer hubby pushed for a breakup, while she wanted to work on their issues. "She just felt he wasn’t there for her when she needed him most and he felt the same. It’s so sad, but the illness really did come between them," a source dished to the mag.

If Yo ever needs support, she can turn to none other than Lady Gaga, who tweeted "you are stronger than hell and we love you" to the ailing reality star.

In our opinion, David Foster doesn't deserve Yolanda in sickness or in health!
