What should I do?

[genuwine]

My ex moved back to California and I currently live in NY.  He filed for divorce (YEAH!!!) and we had mediation set up and also trial date..(10/03)...I was allowed to appear by phone and he was a no show.  Judge removed case from calander.  There is NO custody established nor support.  I have filed the response papers and have been waiting for his reply for 5 months, nothing.  I have recently found out he was in a 90 day rehab program, this is habitual with him.  I have refused my son any contact with his father as the man finds it necessary to bribe and promise, let alone the child is going on 14 and the father treats him as though he is 8 (hello, grow up huh?)  I also will not allow my son to visit as the father may try to keep him.  How to I get the process back in the court for judgement?
