It is always okay to say "That (D) is not what I want. But it isn't up to me. It takes two to make a marriage, but only takes one to make a D."
That is what I would say to my W. That way she knew I was still against the D, but that there was nothing I could do to stop her. And it also conveys to the WAS that all of the work for the D is going to fall to them. The filing, the paperwork, etc.
When it comes to D, if you are opposed, then you do nothing to help it move forward. Don't actively hinder it though.
