Please give me legal advice. Should I fight against injustice that has happened to me?

I respect my father-in-law Prof. A.C. Rajashekar [Professor of Law and a Senior Advocate] very much. I have touched his feet twice during my 1 1/2 years of marriage. God promise I love my beloved wife even though she is completely deaf. Before my marriage my beloved wife, her father, her mother, etc never told me that she is deaf. They diverted my attention by telling me that she is having defective speech problem. I am the boy who married her and they should have told me before hand that she is deaf. God promise I was never told before my marriage that she is deaf. After my marriage during our honeymoon in Ooty she herself told me that she is hearing impaired. I admit that it is my mistake also that I never questioned her about her deafness. I believed everything that my father-in-law told me because he is a Professor of Law and a Senior Advocate. When I came to know that she is deaf I was very much shocked. When my beloved wife told me this she was sobbing uncontrollably and requested me never to leave her. I somehow consoled her and I promised that I will never leave her. I told her that I love her and I will continue to love her till my last breath. But now she has sent court summons making a prayer to the court to dissolve our marriage? It seems very strange behaviour. I love her even now and I prepared to give my life to her to prove my love. I don't know how I can prove my love to her. I have washed her underwear with my own hands some times even though we are having a washing machine. If I did not love her I would never have washed any of her clothes. How I can prove that I love my beloved wife? Very eminent and learned Professors, Lecturers, Instructors, Attender had attended my marriage from my side even though I am just an Instructor. From my wife's side also about 500 guests including very eminent people, Professors, Bank Managers, etc had attended my marriage. God promise I want to save my marriage and I want to be married to only my beloved wife till my death. My beloved wife is telling me that I should become "Ghar Jamai". I have my self-respect. I don't want to sacrifice my self-respect by going and staying with my beloved wife in her father's house. Please advise me.
