Mermaid,
You pushed his buttons when you sent the email about the boundaies. Step back and wait patiently to see if he has actually done any of the "hard", but necessary, work to file. If he thinks a divorce is a simple deed to do, he's got another thing coming, especially when it comes to paying for the lawyer's fee.

If you don't want the "D", don't say a thing about it. I suspect he may be blowing smoke, but time will tell. Yes, it's sad when it's been 4 years and he's now decided w/o any discussion w/you that he wants a "D". I can understand your statement about it being sad, but a relief as well. You've fought the battle and it's not over yet.

Please take care of yourself. Do sit quietly and wait, for more will be revealed to you. Your h is still in replay and can't see the forest for the trees.
