Savingme, I don't know much (actually nothing) about finance and legalities but getting away from this guy can only be a win. Yep work the finances the best you can . . . but . . .get away . . . .far away . . .and stay away.
My extended family had a vineyard at one time worth some 18 million dollars. A relative ran it into the ground. This last Christmas, the same week my Dad received $800 for his share of this ranch, I had dinner with a very wealthy family. They must be buzzilionaires from the wine industry. They had an amazing house in Mexico. In the middle of dinner the husband called the wife a f----- c----- (and more). . . . . . Thank you very much, I will take the healthy relationships I have and they can have the buzzzilions of dollars. . . . . no it isn't fair, but I think it isn't fair in my favor.
Get to an alanon meeting; work with that lawyer; take care of you and let us know how things go.
May many angels bombard you. This is very tough stuff!
