Ok, here are a few nuggets for you to think about. Don't look at these as things I'm saying you should do, but rather think about how your wife might think and feel about them in both the short and long term. Also, consider your most recent e-mail was at least somewhat on the confrontational side of things.
Also, remember my belief system. I do not know if you and your wife share it.
What if you put your wedding ring back on? What if you changed your mind about how assets are divided (while abiding by the law)? What if you did give your wife a small gift every now and then?
Here's my point. Are there ways you can pull some of the confrontation out of this divorce process? Is there any way you can send signals, even now, that you care about HER.
From some of the different materials I have read, it is not at all uncommon for a wife to dream of "running away and leaving everything behind".
Again, this post is not about suggestions. I'm just saying if you could see some hope for this girl in your future, being demanding may not be the way to respect.
