Court was today....
I had all of my documentation in order. I stayed on task, only answering what the judge asked or explaining an issue that the Ex brought up.
Ex, however, did not do himself any favors. At one point the judge told him that she wasn't going to argue with him about a particular issue.
And she asked him why, exactly, he believed he did not have any responsibility for paying for his children's medical care...
I provided proof that I had advised the Ex re: medical information, I provided proof that Ex had been less than amicable (by refusing letters sent/returned unopened mail, by not opening emails for 21 days *thanks to readnotify*)
I don't really care about the decision. I am more proud of myself for not being drawn into a peeing match with the Ex, not responding to his accusations and falsehoods! I am more proud of myself for being calm, and being able to get through this whole thing without crying (I typically cry easily...heaven help me if a sappy commercial comes on the TV.

)
The judge said she would have to review all the evidence/documents and would issue a decision; she did advise the Ex that he did owe for the out-of-pocket medical, she just needed to review the numbers.
