I want to know how to break relation with family and will both

I am 30 year old but still I am not living my life on My terms. My parents always pressure me marriage t someone they want but I always denied. They always want to gave me job opportunity but I denied reason is if I live on my term including job or women so they always told me that they will kick me out from their home. Literally no one support me at home. Well parents gave me opportunity for job but I denied it because they want me to do a sweeper job or peon job but I am educated person also they want me a buttering job for the life but I don't want , 2nd what they wish I don't like, inshort lifestyle and regulations they want I am opposite of it. I am looking for job that I am not more dependent on parents but is enough is enough, every time my parents specially my father always said in anger he will kick me out of the home, tell the world about it even he will spread bad things about me. Literally I am tired of it. I don't wish to live with my family even I don't wish to part of the will of the property. I am not greedy person at all . I just wanted that I want to live my life on my term but this thing my family and my father specially don't like someone they threat me abuse always they will kick me out from home . So I decided after limit cross that I wish to break all relation with my family or I will do something bad with me. Since I child I hear it from my father that he will evict me from his home if I something did bad with their family legacy and dignity. But I didn't do anything like that just wanted to live my life on my terms. Even I discussed with them but throw object breaking thing and hyper on it. Even my father in a extra affair with someone who is 20 year younger than him even she is married but my father always said that she black mailing him but I don't believe that because my father write her name in his phone " my heroine " . I just wanted to live my life on term if they don't want me so I wish to leave my family and break all relation . I am happily wanted to leave the will and family I am not greedy person. I just wanted a life on my terms that's all. How and what I do I do t know. I don't have friends and any support nor a girl In my life but still want to leave because I am not happy from inside ,my family want me live a life like puppet if I don't so they will kick me out from home or blame me if he will die. I am stuck. Totally. I even make a call to lawyer 5 times different lawyer so they said we can't do anything on this. So I asking it what I do to break all relationship with family and their will.
