Why to sell both kidneys and if you do that how will you survive?
Best for you is to keep fighting the divorce cases on merits, even if both cases of divorce filled by both of you fail you should not worry, wait for some more time to file fresh divorce case on the basis of new facts.
As far criminal complaint case u/s 498A IPC is concerned better withdraw the quashing petition filled in the High Court as that will never get you out by any way for another couple of years, better fight the 498A IPC complaint case on merits as the onus to prove you guilty is on the prosecution, wife. In the end that case will fail on merits and you get acquitted, after that you can file divorce case on the new facts for cruelty and will get order for divorce easily.
No paying huge sum to wife after selling both kidneys, just take legal help from experienced nd expert lawyer rather typical ones who is taking you nowhere.
