In our country, finding FIR is always a bad idea. Now you have a first hand experience of it. FIR and courtrooms are for ultra wealthy who can pay and hire the best lawyers, and the lawyers take care of everything without causing any hassle to them.
What counter FIRs they have done against you? You can apply for quashing of FIR on the basis that it was registered as retaliation by the other party and is not genuine. I am not a lawyer and do not know how it works, but have heard this is an option in case of false FIRs.
