Dismissal Of Divorce Case- If Petitioner Absent On Issue Hearing

My mother is the petitioner of this divorce case and no alimony/settlement was demanded from our side, we didn't agree to reconciliation which was the last date, so that failed. The next date is the issue hearing from petitioner side & needs her to appear. But, now we’ve decided to not continue the case anymore. I see two options 1. Withdraw petition 2. Dismissal through absence. I am for the 2nd option, as this means no more hassles as the court will dismiss the case if my mother doesn't appear in following dates. Is my understanding correct? Is there any repercussion? I understand it leaves us with an option to show suitable reason for our absence in the future and re-open the case, on the other hand, if we withdraw through a petition, that means, we will can never pursue similar case under same ground, and also, under rare scenarios,the opponent may demand penalties or court can impose fines/court fees on us for wasting their time. Please let me know if my understanding is correct.
