Practically speaking RCR won't help you.
The time she file RCR, she will file maintenance in your case.
Your money of filing RCR will become zero.
Better to file Criminal cases against her.
Manage this with your advocate and then see the results.
She will run behind you.
Frame charges that she ran away with all money, ornament, your mom's jewelry etc etc.
Do it bro. U will surely get the results.
Either she will come back in your life to stay with you or this fight will end with divorce.
Filling RCR will consume your minimum 2 years running behind court and advocate.
