I would ask the court for clarification.  Generally sepaking those matters are spelled out - phone calls etc., - in the agreement.  For example, when one parent has the child the other should be allowed contact via phone to say goodnight, etc.  Here is the thing: if you stop access he will show up and probably even go to court to try and enforce what he thinks is the agreement. It may be the tactic you need and you should discuss it with your attorney so that you are sure that you are not in violation of the court order.  Good luck.
