The first thing you need to ask yourself is, do you want to stay married? If you won 10 million dollars, would you want to stay married?? If the answer is no, then get out of your marriage. If you want to stay, the first thing you both need to do is get financial counseling and you need to be in control of the money so he can't spend it recklessly. You both need to write all spending down and keep track of all money and where it goes for 2 months...even a cup of coffee. If he's not willing to do this, then you should leave and take care of yourself. Money causes many problems in partnership. Only by what's absolutely necessary. I hope it works out for you.
