Im currently 18 (M), and i feel like my father sees me as a dissapointment. Ill start from the beggining for some context.

My parents were divorced for the first six years of my life and i saw my dad maybe once a year, i grew up with my sister and my mom and saw my grandfather as my real father at the time because he would be the one raising me. My grandfather is a humble more old fashioned tyoe of man and i really resoected that. My parents got back together when i was six and i moved to the middle east. My life changed completely as my father is very wealthy and hes the oppose of my grand father. When i was growing up id hear my father make racist, sexist remarks to other people in front of me, he'd yell at minimum wage employees for the smallest things and most of all didnt really treat me with much respect as in his eyes i wasnt really a man (this went through ages 6-15).

Throughout this time i would get really good grades and started working out, then in 11th grade (i was 16) my parents split up again, they still lived in the same house but my mom was never home. My grades became a lot worse as I hated being at home in general. I would spend all my time at the gym working out and my father hated that. He said that if i dont finish high school i will have no one in my life that will help me and that he will cut me off for good. Today we had an argument because i was away from the house for 3 hours (at the gym again), he said that ill become nothing more than some taxi driver and that from now in im all on my own. My finals are in a month and im only at risk of failing physics (i take IB btw). Im not really sure what to do because i hate living off of his money, and if i do graduate ill go to uni still off of his money which is an idea i dont want to accept. Everytime he speaks to me i feel like a dissapointment because of one subject that im not doing well in. Right now we are at the stage of where he cannot control his divorced wife and his daughter doesnt really soeak eith him anymore so i feel as if he takes out most of his anger on me. If i shut a door too loud, breathe too loud or do something of a minor incoveniance he starts getting agressive with me.

I shouls clarify that this is my perspective so this is bias, theres a lot of things my father went through in his life to make mine easier.

So i guess im writing this to ask what i should do now.
