Can wife withdraw her appeal filed in sessions courts by her against acquittal of husband u/s 498a

My wife filed a complaint with women cell, Delhi. Same got registered as FIR u/s 498A / 406 IPC against me and my family. We were discharged u/s 406 IPC and charges were framed u/s 498A only. After trial lasting about 10 years we were all acquitted u/s 498A. No appeal was filed by the state, then wife filed an appeal against acquittal order after delay in court of sessions judge at Delhi, her delay was condoned since she is a female. In the appeal we appeared and have even filed our written arguments last year, wife and her lawyer prolonging case by not leading there arguments. Hon'ble ASJ said that we do not need to argue because we have already been aquitted and the wife is still to prove that her appeal has merits / needs to be heard. After that if required ASJ said we can argue. ............... Now wife wishes to resolve all matters with us ........... My question is that can wife withdraw her appeal filed in sessions courts by her against acquittal of husband u/s 498a .... no appeal was filed by the state and the state / prosecution branch had not given her any written permission to file an appeal against the aquittal order by the MM in trial court ...... plz do reply .... rgds
