Divorce petition Filed with mutual consent

A petition for divorce with mutual consent was filed in Nov. 17and has been filed and 6 months time has been given for reconsideration. We have to live separate during this period which is being done. No idea of reconsideration is there. Will the divorce granted on the fixed date or further extension would be granted.in the petition wife is the ist petitioner. She has mentioned that istridhan, alimony taken. Will not claim any maintenance. Custody of two children will be responsibility of the husband. Will not file any case nor any claim on any property. On the fixed date after 6 months absented from the court. The appearance date now 2 months ahead. Now she says that she does not want divorce but husband does not want to withdraw. What is the course of action. Can she contradict her admissions about alimony, maintenance etc.She did not appear on last two occasions .My lawyer says the petition will remain alive for 18 months and court will grant another date on our request. I am in a fix whether it can be stretched for 18 months.Pl.confirm.
