don't ever leave the house!!!!!!!!!!!!!
it's your house as much as hers, if you leave, it shows intent that you wanted to leave.
Divorce courts are inherently against men, don't give them anything extra.
Do not do ANYTHING without at least talking to a lawyer. Yes, lawyers are expensive. Making legal decisions without a lawyer is much more expensive. This is a couple hundred thousand dollar decision you are taking, couple hundred to even consult with a lawyer would be money well spent.
