From the information that you provided, you may have grounds for an annulment. You will need a third-party witness to provide some type of affidavit to the effect that your wife agreed to have children , and in fact , now says that was not true.
If she will not contest the annulment, I believe we will be able to get the annulment.
In any case, you could elect to file for divorce and not wait the year. Please contact me at 212-370-1660 to discuss the matter at greater length and to arrange for an appointment with you and your wife.
