This is hard, I know. Please go see an atty as soon as possible. Do not waive your rights to counsel. Do not speak to him about anything legal and do not let his threats of filing a contested D scare you and do things "his way".

Do a Google search in your area for attnys that are very specialized in contested divorces and custody issues. Look for reviews by former clients and use the public record as a tool. Interview as many attnys to rep you until you find the right one.

This is where you will need to separate your emotions and your logic. As a citizen of this country you have every right to obtain legal counsel for ANY legal matter. Let your WAS babble all he wants about what he wants.
