Re damages suit

Sir, I am a converted christian and got married with a christian girl we both are from same community in India. After a short span of time due to differences in life style, thinking etc we got divorce by executing a divorce deed before public notary which was signed by both parties and witnesses. This custom is prevailing in our community in gujarat. After some time I approached passport office for deletion of spouse name from my passport for which they asked divorce decree. A clause for passport is mentioned in our divorce agreement. So we contacted my x wife and her parents for their co operation in this matter. They became evasive and started fighting with us. Hence we call police and filed chapter case against them and later she filed many cases against me and my family including DV, 498 etc but we acquitted ourselves in all these matters after years of fighting. My petition for divorce decree case is still pending. My question is whether I can file a suit for damages against my x wife for breach of trust and for filing bogus cases against my parents who are senior citizens. How much is it worth to file a suit for damages in this situation and how much time it takes? Please advise. I will appreciate all your help! Thanking you,
