You should only be focusing on your documentation. Again, if he wants the divorce, then he needs to prepare his documentation and present it in the proper format. I think you are very wise in waiting to see how he responds to what you present and go from there. Don't be surprised if he comes up w/stuff that can be seen as petty and finds excuses to drag this out.
Like most of them, he will not: 1) do the hard work of presenting his information; or 2) it won't be a thorough job. They think a divorce can be done w/the snap of the fingers and do not realize the amount of time and work that goes into separating everything. I hope that I am wrong and he'll be ready to present his data so that you know where he stands and what you will need to do.
Hang in there!
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
