I 2nd Jack's suggection of a lawyer.
I am not a lawyer but I think you sound like you need one.
As an aside, I cannot imagine the climate in the house if you both live in it while divorcing. That's got to be something like the movie War of the Roses. Do you divide up the teritory with common areas like kitchen and bathroom? I don't know the answers.
Hire and talk to a lawyer, but in my mind, it sounds like there's a risk of a domestic violence dispute. And then there's the usual shot gun approaches that may be used, she'll say you are an alcoholic, you do drugs, you have other women in the house with you. Whatever.
If you have never been through a divorce before, my suggestion is this.
Step #1 Hire a divorce lawyer
Step #2 Listen to him or her and do as the suggest
Step #3 This one is my person thought, so take it as you want, but I would suggest you tell you lawyer not to bother you with things that he knows are just smoke and you don't need to know about them. If you read and get upset about it all during this time, you will drive yourself crazy. She's gonna request you give her the universe and who knows what else. You have to remain cool and calm in all of this.
I do not envy you and I wish you the best of luck in this!
