It is not appropriate to use the children as intermediaries. As a former judge, I can tell you that such would tick any judge off to no end. Tell your ex that if he won't communicate with you to co-parent, that you will get an attorney and file a Motion to Modify Decision-Making from Joint to Sole. He is not exercising his decision-making right now as it is anyway.

That is completely inappropriate.
Sit down with an experienced family law attorney to discuss the situation and any possible steps to take.
In no way am I offering you legal advice, and in no way has my comment created an attorney-client relationship. You are not to rely upon my note above in any way, but insted need to sit down with counsel and share all relevant facts before receiving fully-informed legal advice. If you want to be completely sure of your rights, you must sit down with an experienced criminal defense attorney to be fully aware of your rights.
