There is a book (whose name escapes me at the moment) written by a male divorce attorney in which he details things a wife can do to her husband pre-, during, and post-divorce to absolutely ruin him in almost every aspect due to the gender bias that exists in the Family Courts today. You seem like the person this author was writing about almost exactly.
The best advice I can give you would be to get educated - FAST! - on the divorce laws in this country and in your state, specifically. Also, try to find the nearest Father's/Men's Rights group to illicit advice and to get more resources for what you are about to experience (it'll probably be 10x worse than what you've already gone through). And, as alimonyman said, try to find a top-notch lawyer.
