I'm (fairly) recently divorced. I understand that you will have a hard time affording a lawyer.... I hate to tell you this, but if she has a lawyer and you don't, you are DONE, dude.
Find a way to get a lawyer. The one thing I can say about the legal system as far as my experience goes is that it doesn't make any kind of sense from a layman's point of view. Get a lawyer. Seriously.
