Mutual divorce

My and my spouse has filled for MCD. We have shown we were lived together for 20 days (9 march 2019 to 29th march 2019 and separated thereafter). We filed the petition at the court on 27th of July 2020 and it is clearly stated in the petition that there is nothing pending between both parties and each other belongings are exchanged already. There is no mention of alumni or anything. Now, we have been through 3 rounds of counselling. During first round, she said she wants divorce. Then she did not turn up to court for next 4-5 hearing, but I was present at each date. In the second round Of counselling after 5 months, she mentioned that she wants to rethink about the divorce, and she asked for more time to think in front of judge as well. (Judge sounded like he is not in favour of the time for extension. Even counsellor said you had 1.5 years to think, didn’t you make your mind?) Now, it has been already more than 6 months since filing of mutual consent petition. When we reached out to girl side, they said they want money which was spend In marriage. Her advocate also mention that they will withdraw the application if it is not sorted. My questions - 1) can they withdraw petition unilaterally post 6 months of cooling period? 2) what options i left with if they withdraw the petition? 3) is there any law by which i can accuse them of harassment or cruelty? Please let me know your views. Also if u have any way out, please comment with the solution, I will reach out to you. Thanks in advance
