Really appreciate your willingness to save your marriage.
You can stop the divorce by not consenting to it on the next hearing date. Tell the court that you want more time to Think before the final decision.
The mutual consent petition can be in the court for 18 months.so you will have enough time to convince your wife. For that you should ask your lawyer to buy time in the court once it is 6 months, i.e on the next date, by citing the reason of reconciliation.
You can ask for mediation / counselling in the court, do that with the help of the counselor or mediator you can speak and convince your wife.
Also can ask your wife to come for marriage counseling with a psychologist other than the court counsellor.
Finally if she still demands for divorce, you can opt out of existing petition and the court will have to ultimately dismiss the petition.
At the same time if she is determined can file petition unilaterally which will take few years trial.
