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 further.
