New York State requires grounds for divorce. She may be contesting the grounds for the divorce.
I strongly suggest that you seek an attorney-mediator to handle your divorce rather than “do it yourself”.
This is too important a matter to leave to self help.
If you are living in the NYC metro area, please call me at 212-370-1660 to arrange for a meeting
to discuss the matter at greater length.
