This week on "The Real Housewives of Beverly Hills," Yolanda Foster admitted that she and her husband David were having relationship problems.

The former model said that she got diagnosed with Lyme disease right after they got married, and it took a toll on their marriage. The mother of three said that the music producer does get impatient and that she understands because the two of them used to do everything together.

On Dec. 1, David and Yolanda released a statement announcing that they are divorcing after four years of marriage.

On her Bravo blog, Yolanda said that it was "surreal" watching David and herself from six months ago and fast forwarding to where they are today. In an earlier episode, the two went on a romantic trip to British Columbia, and Yolanda said that sharing that experience with her mom and sisters-in-law was "exactly what the doctor ordered."

The 51-year-old also addressed the speculations about their divorce and said that they are "simply untrue."

"David has been one of the guiding lights in my journey and even though we ran out of steam I will never allow anyone to discredit his persistence and commitment to my healthcare," she wrote, adding that she was "eternally grateful" for his support.

Apart from dealing with her relationship with David, Yolanda's illness was also the topic of much speculation from Lisa Rinna, Kyle Richards, and Lisa Vanderpumpt. Rinna implied that Yolanda might have Munchausen Syndrome, a disorder wherein those affected feign illness to gain attention or sympathy.

In the next episode titled "Will Power," expect more drama to go down as Yolanda will hear all about Rinna's comments when Eileen Davidson inadvertently mentions it in front of the former model and the other women. Later, on the eve of getting her breast implants removed, Yolanda makes a startling announcement to her children.

It appears that the announcement may have something to do with Yolanda's will.

In the season 5 trailer, Yolanda can be seen talking to her children about her will, telling them that she wants to be ready if anything happens to her.

"The Real Housewives of Beverly Hills" airs Tuesdays at 9/8c on Bravo.
