Dear friend, empathizing your situation, I truly understand that at this point in time you have only 2 options, either to dare the storm or let it blow you out.
However, my two bits apart from the suggestions provided by my above friends are as follows:
1. don't display mental pressure in handling the situation as it would motivate your wife to do what she does not want to do; albeit this advice is more psychological than legal; and,
2. in case if you feel that grave injustice has been done to you and your parents and in an event if an FIR involving your family is filed, then as suggested above by one of my learned friends, go for quashing to the High Court based on the recent judgment of "Geeta Mehrotra & Anr. vs State Of U.P. & Anr. on 17 October, 2012"; and,
3. finally, you may file a counter case under Sections 193, 196, 197, 198, 199, 200, 203, 209, 211 and 120B of IPC, for filing false case against you, the punishment of which is up to 7 years.
