I am sad that you are being so sorely used by the society, your ex, and former congregation. If nothing else, this should show others on this board the lengths to which the WT will go to hurt those who won't play their game the way they want it played. Lying doesn't count if you are doing it for Jehovah's people, you know!
Good luck to you-take the excellent suggestions of providing proof of WT teachings from their own lit. It isn't top secret, its in black and white. And YES, do go to the press when it is concluded(or at an appropriate time that won't hurt YOUR case).
The judge has a right to know when they are given perjured testimony and it will discredit JWs in his court for ever after. You might want to show your ex/his elders your proof before you go back if it will give you a bargaining position. They may give up the attack if they realize how much damage continuing against you, with their their lies clearly showing, will do to the org.
