This seems sad to me. I have met them both and they seemed happy for so long. I always had a feeling that it may not work for a few reasons. For one, Shiva is also an actress and a good one at that..she put her career on hold for years while raising their first daughter. When Dylan stopped working on The Practice I think she may have thought and hoped that she could pursue her career more...and then they had their second child, another beautiful daughter. But shortly after, Dylan took on another TV series, and was once again an absent father/husband. It would make sense that perhaps this was the straw that broke the camels back...but I'm just speculating..Lastly, I found Dylan to be a dark and moody person, and Shiva an absolute sweet, friendly and generous woman. Without knowing the real reasons they are Divorcing, I don't think he was as supportive of her acting as she was of his.
That being said, I wish them both happiness and love in their futures apart from one another.
