wife not coming court for witness in criminl case against me

My wife had filed a case against me u/s 506 (2) and 420. Case was absolutely false and all of the incidents she mentioned in FIR and 161 statements her are fictitious. I have enough proofs to show how incidents she mentioned in her complaint never happened or couldn't have happened. Police filed chargesheet around 6 months ago and case started 3 months ago. Charge sheet doesn't have anything other than 4 statements ( one for her and threefrom her family members). Charges were framed on very first hearing and I opted for trial. Next date my wife was summoned to give her evidences. But she started evading court and didn't come court even once to give her evidences. I am waiting for her to come court so that I can cross examine her. But she didn't appear on last 3 dates and on each date I went travelling more than 1500 kms. How long it will go on if she continues evading court? Is there I can call for closure of evidences for her testimony? How many chances she going to get from magistrate for her appearance? Magistrate is already upset with her and told I/O she'll issue warrant if she doesn't appear next date. Is there anything I can do to close matter citing disinterest of complainant in matter? Pls advice.
