Motor accident

I am 28 i travelled with my wife in motor(scooter) .i kept my lane as left corner on travel beacuse some on is tried to cross the road in scooter from left to right so i got a gap in left lane i slightly moved but the opposite scooter came backward unfortunatley so i am unexpected then i hit that motor.so both of the scooters are falldown with injury got both scooter and the peoples.but it is not my fault.my wife got more injury and me got a little but we dont know about the opposite parties.the opposite party also couples and so because we are unconcious.so peoples from the nearer are helped the accidental both.then they told me to go and give first aid to your wife because you both are ok but i worried my wife got blood from nose and leg so suddenly i taken my wife and admit to hospital for first aid.i dont think opposite party beacause of my wife injury so i leave.i forget to inform the police also.2 days later i got a call from police you to meet the SI because of the instance.so went to police station the opposite party filed me a case .now i got ipc 279 and 337 because of hit and run and i hits a lady who standing to cross the road like this.but true is i hit the scooter and the mistake also from opposite party.so the police told me to surrender the scooter and to show ghe rto.the process is finished.but my question is how to solve and how to prove it is not my fault and the statement is also fake.FIrst thing i am not hitted a lady who tired to cross the road and but i hits the scooter and second thing i am not hit and run ,peoples told me after given help for me and my wife you should go and give first aid to your wife like this.so totaly wrong in statement.i asked one wuestion to the police i want to file a case to opposite party for the lie.but he told me it is accident case if you given also same ipc 279 and 337 come to You. Please give me the solution.he complained ,me hit his wife crossing a road so no chance to clian insurance for scooter .If opposite party ask a claim means what to do.My side is not mistake.
