Should i stay or should i leave?

I am 24 F, and i have been living with my parents for about 10 months now. Prior to this , I was working in UAE. I fell in love with a german guy and my family found out and of course their reaction wasn’t the best. Eventually, my mom told me she is okay with it and so is the rest of the family, and that my dad is the only person needing convincing . She said that she tried but he wont listen to her and i am the only person who can get him to accept. My father did not speak to me at all since he found out about my lover. My mother told me that the only way to get him to accept is by being in front of him and speaking to him that way. I visited india for 10 days and nothing worked out. My dad remained stubborn and was clear with his side of the family and society mattering more than my happiness. He also said he will never accept a guy that he has not chosen for me. And of course there were the racist remarks with him being a german. I went back to the UAE, and my mother convinced me that i need to be here for a longer time and asked me to come back, she promised me that she would always support me and that i should trust her as a mother. Which i did. But once i arrived (i left my job btw), everything was uhm off… from the moment she picked me up from the airport, the energy was extremely off. A couple days later, there was an argument at home , to which i suggested staying in a hotel room for a while. This ticked off my mother and she hit me to the point that i bled, i could not breathe, i had bruises and scars all over, i was begging for her to stop, but she did not. Instead she told me things like she should have done this long ago and broken my legs and hands. She even kept punching my abdomen asking me if i was pregnant in attempt of "killing the child". This experience terrified me to say the least. She apologized and never hit me again since that day. Things have been okay ish. There are days when she cusses me out and most days she treats me very kindly. Me and my father are not on talking terms, i mean i did try to speak to him and get his acceptance but he is too stubborn… i am also very close to the rest of my family and especially my grandparents. They have raised me and have been nothing but kind to me. But, my grandfather has told me that when it comes to this matter even he cant do anything since my dad is the one who can get me married and no one else. My mom is extremely scared of my dad, and my dad has threatened her of divorce if she continues to support me. The whole family feels powerless because of my dads decision and no one can say or do anything. I feel incredibly stuck. I love my family so much and they love me too. I am very afraid if hurting them. And now , i have a new visa in my hand. I am stuck between running away and sacrificing my freedom and happiness for the sake of my family…
