File RCR. Thats the only option you have got.
If she wanted to stay only with her parents, why did she marry you? Why did she spoil your life?
If they threaten you. Dont be afraid. Any case they file against you, nothing will happen.
Only thing is you will lose time behind court cases. thats all.
Rest all humiliation etc are a part and parcel of married life, some you see while staying together, some you see while you are in court. But decide for yourself, is she worth it?
Is running behind her any more worth? You should have understood what she is long long back, 8 years is long time to understand a person. The moment you came to know that she dont want to stay with you, but insists on staying with her parents, then itself you should have gone ahead and filed divorce. By this time you would have gotten divorced.
Anyway better late than never. File RCR, give 2 weeks time for your wife to come back to you, by the end of 2 weeks, file divorce based on desertion.
No question of paying 10k to her, as she left you on her own will and wish.
Love affection etc are nothing, they are of value only when reciprocated both ways. So dont worry.
Keep in touch. All the best.
