G, You need to protect your financial interests. Go talk to a lawyer and see what you can do to ensure this. Remove his name from any of your accounts and set up a separate bank account, if you haven't already done this. If you have access to some of the financial documents of the company as it is right now, start making copies and put them in a safe place.
G, you can still stand and protect yourself. If he's in mlc, he will spend like there is no tomorrow on stuff that is foolish and will only satisfy his craving for fun and entitlement. He will not think about you or how you will need to scrape by. Protect yourself. This is now a business deal.
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.
