You filed RCR on the basis that she left you on he sweet will and not by force. In counter to it she filed 498A now tell me whether the 498A complaint has been turned to FIR against you or not wait till that and try to not to get it turned to FIR as SC has now given strict dirctions to all courts and Police not to arrest any body except with court orders in 498A cases as these cases turn out to be fases many of the times and its cunviction rate is very low the misuse of woman protection laws should be prevented.
On the other side let the spouse file her WS and try to get them defeated on the grounds of not returning to home. In case you get it established that she has moved out of your home on her own will you will not be bound to pay her any maintenance. In that case your ground for getting Divorce also will go strong in your favour. Your Advocate has rightly advised you for fileing RCR in case he i having the same plan as I have narrated you as above.
Please accept and note the path is tough but if you concentrate on the objectives you will not loose at all.
You can consult me any time if needed for the further course of action.
