498A + 354D FIR & Look out circular

I am a NRI had dispute with my wife and she was living in her home since 2015. She came to live with me overseas only for 3 months last year and came back to india. In March 2018 I came to know about her extramarital affair and confronted her family by emails and phone calls. I have electronic evidence of her adultery as videos of her having sex with other man in her home. She threatened me of cases. They filed 498A+354D on me on 10/4/18 with false allegations of dowry and harrassment. Main allegations are verbal abuse and dowry harrassment. Look out circular was issued but I wasn't aware of it. I decided to file divorce and came to India on 3/5/18 but was arrested in the airport and came out on conditional bail. Chargesheet has not been filed yet. Police have sent the videos for forensic analysis to confirm if that's her or not. They say they will decide to file chargesheet or not only after getting the results. P.S. I have not taken any dowry from her but instead they have taken money from me. Please explain the following; 1. Should I go for quashing the FIR or wait till chargesheet? I have strong evidences like bank statements of sending money regularly to her, emails asking her to come and live with me and etc.. 2. How to cancel the look out circular so that I can travel back for work abroad? 3. Should I file HMOP immediately or wait to get results from forensic department? I got to know that they filing DVC and Maintenance case as well? Please advise. Your suggestions will be highly appreciated. What possible legal options are there for me to get relief and go back to work.
