Mila, As hard as this is, you have to put on your business suit and look at everything, including your marriage as a business deal (contract) that has been broken. You have to leave your heart at the door when discussing the financial aspects of the separation/divorce. I know that you want to shake him until his eyeballs roll on the floor, but it will do absolutely no good right now.
We all wanted to give them an opportunity to realize what they were/are losing, but they are so lost in their "lust" for the ow and their other addictions, they just don't care at this time.
Protect yourself no matter what.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
