Try to relax. This is just the way the justice system works. That judge doesn't want to risk being responsible for lifting the order and then you kill somebody, so they cover their but by ordering an evaluation. Sounds like standard operating procedure to me.
I know, it doesn't work the way we envision it; I learned that last year when my brother had to defend himself against a false charge.
Have you contacted a father's rights organization yet? You really really should, they can offer you valuable advice, this is not an uncommon situation.
