Brothers wife and family harrasing

Since my bro got married 2year back, my sister in law behavior was suspicious, she intentionaly used to post video or messages in our family group of relatives playing victim,she tried to make good relations with relatives but in the family of ours,she used to be aloof and behave as if living in hotel,she used to be in bed n do dramas,cry,be ill, n my mother used to cook clean everything, we had a maid for help,but here my sister in law used to play victim that my mom and dad are harrassing her and my brother supporting her,me and my young bro ws upset over her behaviour. One day, wen I was at my home for the occasion of festival,me and bro had a fight over petty issue and she came in between our fight and started abusing me verbally and tried to hit me, I just said stay out of our fight and do not come between us, she started saying why she should not come,it's her house, even I said as a daughter it's my house too,later we sorted out the issue,n everything was fine from our side n we forgive, but she was in revenge seeking mood, I avoided visiting my parents since than,used to go only when my sis in law was at her maiden place,or hardly on birthdays of my parents or functions,shadi of neighbour, she used to do dramas in house fight over pety issues, finally my brother got seprated on rent, my parents were in peace, she was pregnant and delivered baby,me and my hubby were out of her n brother life but than she and her parents started spreading lies about me and my parents again,2mnth back,she created problem of us with my in-laws, lies and fight between me and my bro in law wife,telling them lies,harrassing me and telling my in-laws to not allow me to go to my parents,they will put case on my husband and me for creating problms in their married life or they will put dowry case on my bro and parents, my bro is in love with her and totally influenced by her, she has saved message s of my brother n me whr I told my brother that why his wife is creating problm at home n hw they should respect parents,no one should tell me that I cannot go to my parents house majorly I used to avoid talkin to her most of the time,bcoz right from beginning her intention was to create problm and separate,her parents used to disturb my hubby for little fight between my brother and her, once she bored her nails on my brother chest, she is vry aggressive and abusive,I told my hubby to stay out of my brother life as it used to disturb our life,n told my bro to ask his in-laws not to disturb us. Aftr her baby,She and her parents are harrassing me n lying people that I want my parents property(in fact they ask my hubby,why my parents are not giving my bro the other house) telling my in-laws and hubby not to allow me to meet my parents or they will put case on me it's frustrating as we have not told any of ths to my bro to avoid fight between husband and wife we never interfered in thr life but she is still spreading lies to my in laws and relativ
