Cavallari says she divorced Cutler was the best thing she ever did

Cavallari talked about her separation in a new meeting on "School of Greatness," saying it was "the best thing I've ever accomplished."

She followed up her statement by explaining to the host how her three children "have driven me to be my best self. If I'm vacant, I have nothing to give them." 

With that, she explained, "Being seeing someone I was truly miserable, that won't work for me.  

What's more, I knew instinctively for quite a while that I needed to make it happen.

Despite it being an "awesome" choice for herself, she said it was the most unnerving thing she had ever done.

Prior in the discussion, she considered the split and the more extensive effect it has had on her life in general.

Cavallari, 35, marry previous NFL quarterback Cutler, 39, in June 2013. They share children Camden, 9, and Jaxon, 8, and girl Saylor, 6 

The "Laguna Beach" alum was briefly linked to the then-Chicago Bears quarterback in 2011 after dating him for less than a year.
