Case Against Divorce whose decree has been passed in Family Court in my Favour

My wife has filed a case against my divorce decree which is ex-parte and is in my favour. Here are the timelines: - 2017: I filed a case against her under 'Section 9 of Hindu Marriage Act 1955'. She did not respond. I got the decree in my favour. As per that judgement, I waited 1-year post receiving the decree. She still did not come to stay with me. - 2018: I filed the divorce case in Family court in my city where the marriage had taken place. In spite of sending repeated court notices - she did not receive the notice and also did not respond to the newspaper publication. - January 2020: The family court passed ex-parte in my favour and therefore dissolved the marriage. - March 2021 (after 14 months of decree): My ex-wife filed a case in same Family court in my city stated as "The humble petition to recall of ex-parte Judgement dated XX.01.2020 and decree dated XX.02.2020 .... " My questions are: 1. Someone told me she cannot appeal after 90 days of the passed decree as per Hindu Marriage Act. If so, why her appeal was admitted in the first place? 2. Since my ex-parte was granted in Family court so she can only challenge it in higher courts such as High Court or Supreme Court as per my knowledge. If so, why her case was admitted in the same court? Is it even allowed? Please correct me if have wrong knowledge. Even if she has filed the case - can the same Family court recall the judgment? Or the decree can only be recalled back by Higher courts? And even if the Family court has admitted the case - what could be the possible outcome?
