I would never be the one to initiate divorce, unless I was the one that wanted one (or felt I had explored every other option). But for the FINANCIAL stuff, I think the-sooner-the-better when it comes to letting a wayward wife put their BGPs on.
It goes to the heart of the whole "let them feel what life would be without you" part of DBing, and besides -- it's just plain WISE to firewall your finances to protect yourself from someone in a wayward, entitled mindset in my opinion.
