What after maintenance has been awarded u/sec 125.

I am a Govt. servant and my Basic Salary is 60,400/-. My wife had sued my U/s 498a, 377, 34 etc after 16 years of marriage. She has taken my daughter with her and my son is with me. She has been awarded an interim maintenance of Rs. 15,000/- per month U/s 125 and final fixation/orders are awaited for want of evidence. She has filed a DV case also and proceedings are still on. An FIR is also in force. I have applied for anticipatory bail but the judges are reluctant to grant it as they are hopefull of an amicable settlement, which my wife / her lawyer do not want. She has no evidence to prove anything because nothing such had happened. She does not want to work though she is also MCA. I have also approached Delhi Dispute Resolution Society for mediation. My questions are: 1. will she be granted maintenance under DV act seperately ? 2. Can the maintenance be increased ?? 3. She is seperate since June,2019, when can I file for Divorce.??? If I file for Divorce, whether she can have right over my ancestral property passed on to me ?????
