Richards tells O'Dell, "The hardest thing actually was that [the letter] was so public. It [is] something that could have been dealt with privately ... because these are minors ... it wasn't like a court document, it wasn't a declaration. I purposely went that way to write something personal as a mom ... I was very upset that something like that would become public ... It's a shame it ultimately affects the children and not just the boys. It affects our daughters too."
