I am so sorry about all of this. He's not happy at all because he's been caught and he knows that he has to pay your the $15k. He also knows that he can't get away w/lying any longer.
I like what Between Tears suggested, i.e., a mutual place to exchange the children. The local police station would be a very nice place for that to take place. They usually are moer than happy to help out. You want it to be a very public place so that if he acts out, you will have plenty of witnesses.
I say BRAVO! You handled this quite well. As for the ow, I hope she got the message about coming there. She has no business being there.
