JRuss, good work you sound like you have a plan and I hope it works. I'm glad you aren't going to let her walk all over you.
What I was trying to say in my post was not so much to make any first moves but make sure your intentions are known and you stand up for yourself. I let my wife walk all over me and In turn lost respect and I'm in a bad place now. Be strong and confident and keep doing all you can so you can hold your head high knowing you gave it your best shot.
