Relief against 498A, DV

My wife filled false 498A and DV case against me and my parents. I am only child. Both the cases were filled during year 2010. The progress is very slow. So far in trial court for 498A only witness of wife is completed out of 7. DV has been completed with decree as big amount maintenance and DV happened. I have appealed at Calcutta HC and it's under process with stay of 1 lac one time compensation but monthly maintenance is going as is. I have filled Divorce case at cruelty ground. This is the status at present at very high level. She has a stand in all circumstances that she wants to return back to matrimonial home and somewhere she is also unofficially telling she had done wrong by filling these cases. However I know her malafied motive. She has been very much enjoying the maintenances and she has been simply doing acting to draw judge's attention. She is able to take sympathy from the judge and it seems I am adamant. However, I know what kind of human being she is. Now my queries are: 1. As she wants to return back whether still my divorce case could be diluted on cruelty ground.? 2. If HC stands with the order of lower court for DV, can it go against me during the time of 498A judgement at lower court? But I have numbers of proof that she has been contradicting and that was caught during trial. She didn't able to witness any such definitive proof in favor of filling 498A. 3. Is there any relationship between divorce and 498A case ruining in parallel? Any merit or demerit? 4. She has been filling false execution cases several times for not getting maintenance but I have proof that I am regular. How that can be prevented? 5. Can I not file any case against her on any ground? 6. Finally, reading through the story is there any way out to to speed up the proceedings?
