Hi Soldier Dad, sorry you have found yourself here. There are some good books out there, one that I have heard recommended is No more Mr. Nice guy, there are a few others, but I cant remember them.
Stay calm, and stay focused on being safe, none of this happens overnight.
I hope that you realize that when she says things like I fell out of love a long time ago, shes rewriting your history together to suit her purposes. Do you seriously think that she would do something as rash as call the cops and say that you threatened her? Is there any history of this kind of thing between you two? As far as Im concerned, it is the Marital home and if she chooses to longer be part of the marriage...well, shes the one who needs to leave.
I would contact your legal aid dept and see if they can help you, that way you can tell her that all communication concerning the divorce or seperation to go through your lawyer.
Again, Im sorry that you have found yourself here, take care of yourself, eat enough, and get plenty of rest.
I guess I gave the wrong finger to the wrong man...
