For Restitution of Conjugal rights Should I Wait for Objection from my wife or go with Mediation

Sir/Madam, I have been married for 6.5 years and after our son was born, my wife would go to her parent's home along with son every day from 10AM-7PM and few days every month and few months every year demanding me to oblige all her wishes. After she stayed in her parents home for 10 month, I moved from joint family (I have lost 5 precious years of my son growing up and she has been using him to emotionally blackmail me) and stayed near her parents home for 6 months and she repeated the same and demanding me to live in her parents home. After she went in Jan-2017, I could not tolerate this and I vacated the rented premises in Apr-2017 and filed a Restitution of Conjugal rights in Apr-2017 ( WIth not letting my son to spend time with me, Not cooking at home and asking me to eat in my parent's home / restaurant and torturing me for living with her parents etc). After 2-3 hearing also she has not filed for any objection and my Lawyer tells us to go for mediation. Please tell me If should go for mediation or wait for them to file objection. Thanks in Advance
