yolanda hadid and David Foster called it quit on their marriage after four years. The couple seemed to be doing great and fans were shocked to hear the news. Now, Radar Online is sharing that in Yolanda's new book she is going to slam him for leaving her when she was really sick. Her new book is called "Believe Me: My Battle with the Invisible Disability of Lyme Disease." It sounds like the book is all written, just isn't quite ready for release.

What did Yolanda have to say about David?

This book is coming out in September and Yolanda is going to reveal a lot about David.

She actually talks about how he wasn't supportive of her with all that she was going through at that time. She said that he was too busy and self-absorbed to be involved with her treatments. Yolanda tried a lot of different treatments for her Lyme Disease and everyone was used to seeing it on "The Real Housewives of Beverly Hills." On the show, it looked like David was by her side the entire time.

Yolanda Hadid also shared that she felt like David would totally ignore her on purpose for days on end. In her book, she actually claims that he told her “Your sick card is up.” After this, their marriage was over and they got a divorce. Yolanda even says that he told her something so horrible once that she refuses to repeat it.

Yolanda is obviously still upset by some of the things that he did and said to her during their marriage.

Fans watched their relationship on "The Real Housewives of Beverly Hills"

Fans saw the relationship between Yolanda and David on "RHOBH" and it seemed like a great relationship. There was no reason to think that anything was going on.

Somehow, she was able to do a really great job of keeping it from the cameras so that they didn't see the problems in their relationship.

When the news came out that Yolanda and David were over, fans were shocked. If she is dating anyone new, then she hasn't admitted to it yet. David has been linked with a few various people since their split.

It looks like he is moving on from their split just fine.
