Advice only (Married 3months ago)

I got married 3 months ago. My wife is good but she argue in every conversation. Till now i never argued back or no single time louder. We both talk less now. Reason is From day one he takes everything on her ego and reply unexpected answer to my mother. Even she told that do not touch anything without my permission. So i decide to discuss this but no use. This type of heated conversation with my mother took place 4 times in 3 month and every time my wife says sorry and told me that she dont want to use these type of words and this type of language but dont knw why i do this? (I have no heated arguement with her till now). I got frustrated with this and told that I got married for my family not for only wife and i can't be wife's slave. WHEN THE LAST ARRGUEMENT TOOK PLACE, i told her i can not discuss with you anything now if you can't stop arguing instead of understanding the things that i am saying to her. >When i went out, She took out 7 to 8 tablets of medicines and try to take it. I saw her from window and stopped her. Same time i called her father, uncle, my uncle about it. My uncle and his uncle came my home and make her understand. From last 20 days everything was good but there was little bit silence from all three( mother , me, wife). My mother told me after such a big issue even her father did not visit her. I want to talk to him face to face and want to say what If she do something wrong ? Why dont you tell your daughter to not act like kids. After 20 days(approx) of peace and silece my mother asked her if her father will come on TEEJ because atleast one time i want to ask him the question about Medicine case. So her brother came on TEEJ and there is tradition of Going mother' home so she went there. Today now at 11pm she called me and telling me that your mother want to meet my father and if she do so i will come with him and there will be good arguement and you will see now. She talk to me for 20 mins and after 20 mins i just say Hmm.. Hmm.. after she finished i told her first lower your voice as i am so polite so she said ok and give phone to her dad And her father told me dont make me angry else you will see the result. I told him that i was not arguing her daugher was louder but she start telling me his theories and told me that dont make him to do something else you will face the bla bla (He ignores all my words about her daughter loudness). Luckily i recorded this conversation only. But MY POINT IS- 1. As per our society i am in fear that she will file fake cases on me with his father. 2. I am very simple guy and do not want any divorce or case but a happy family. 3.What if she come back and do anything wrong 4.Situation is not so high that i file a police complain. 5.This situation is So confusing that Only Lawyer mind or experience mind can help me. 6.I am an engineer and doing job so i m out of house for whole day so i can not see what is happening in home -AFTER EVERY FIGHT SHE BECOME NORMAL for some days
