New York would be the proper jurisdiction in which to file. Many people are under the popular misconception that they must file for a divorce in the state in which they were married. This simply is not the case. Typically, a divorce is properly filed in the state in which one or both of the spouses reside.
Since you have been living in New York, for so long, you more than meet any residency requirements.
At this point you should consult with a divorce attorney in your area regarding your situation.
