@Raman – The Problem is Money and Money makes many things.
File RCR and wait for few months. I they don’t respond. Talk to her and file for MCD (6 months both are free).
You can take a horse to the pond, but you can’t make it drink.
The moment you say Divorce.
They will demand Alimony, Maintenance. If you go through LCI there are lots of similar posts.
They might file false cases such as 498a, Domestic Violence. Record all conversations, if possible video record them.
No Alimony or Maintenance if she is working and she left on her own will.
If the case is contested you both have to roam courts for years together by spending your valuable time, money and energy.
If she is not interested in Marital life, I don’t understand why did she get married at all.
