My in laws and husband harass me every day for every single thing in the house, thereby making my life miserable. Actually my in laws has major influence on my husband n he agrees to whatever wrong they says. my in laws always go to my parents home & create issues over there & abuse them without a reason, since 3 years I take care of a 6 years son of my brother in low & since then my life has become more worst, they always come to my place stay for a weeks period, do the partiality between my kids & that boy, & abuse me too that you dont do this for this kid or you don't take care of him properly etc. & for these same reasons they go to my parents & abuse them.my husband is a engineer nut he dosn't work, he left his job, he is a lazy person who cant do anything in life, now since a month forcefully sent me & my husband to a village & ask us to do the farming, there also they tells lies to my husband & asks him to torture me on phone and ignites fight/ arguments between both of us and clearly tells my husband, right in front of me to divorce and remarry but he dosent wants to leave me & if i will aplly for devorce they wont let me & my parents live properly, now the situations are very critical, I a staying with my parents since 15 days & they are creating matters, & they are threatening to kill me & my parents also, My uncles are not taking part in between coz my mom in law is my real buaa & that beople can cross any limits, even this is all happening just because of my brother in law, He is a doctor by profession, he is the master mind behind this game, even he speaks chip about my small sister & family, I am realy afraid of causing problems to my parents, Plz suggest legal implications in this matter and oblige.
