Struggling students: How to handle father's affair and its impact on studies?

Hi Anu mam, I want to share with you my life story because it now killing me everyday. I am 23 years old now and third (unwanted) child of my parents. I have two elder sisters, 2nd sister was adopted by my father's sister and now I have one elder sister only.If I talk about my childhood, I have no good memories, not a single picture of mine.My father has always been busy at our family shop, only source of our income with my bade papa.He never took any interest in my studies, school admissions, parents teacher meeting etc... He was always like a strict father without any strict responsibility on him. And my mother is a very simple and innocent Jain lady who believes in Jainism and God. So in my childhood we were not a united family, we were more like small scattered pieces of a family who were living with no hope and no future planning or future expectations.As a kid, I spent most of the time watching tv or playing cricket. I have feared to ask my dad to buy me a cricket bat due to which I stole money from his wallet and buy my things for which i’d be brutally beaten if caughtI studied in a Hindi medium school which was in front of my house. I studied there till 3rd class and then my mother did some efforts to get admission in English medium school but she didn't succeed. I took admission in another Hindi medium school. I worked hard at my level but never received any support from my parents especially from my father.I passed my senior secondary in the year of 2015 in Math stream with 69% and want to pursue Engineering but my father does not want me to pursue that he wanted me to pursue Law so I took admission at local university and completed my graduation in 2020.During my 1st year of graduation I realised that my father has an affair with someone. This caused serious trauma for my mother and me. We felt this was the reason for him not being interested in our life at all time. In my 3rd year of graduation I founded that my elder sister was in a serious relationship with someone which added to our trauma because we were also facing financial problems that time. The problem arose when 3-4 years ago I came to know that I have knock knee problem in my both legs since childhood. I couldn't tell about this to my family.So now I am unemployed, facing knee problem and depression. I don't know what to do. Should I leave my father for life and look forward to any small job and live my life, make my new family? I want you to give me advice according to my current situation. I will wait for your advice.

Ma’am there are so many conflict that my father’s sister passed away due to some serious health issue and she died very early and my father does not trust on him because he is kind of debauchery person , can sell her daughter too to whom I’m in love with since we’re together from 5years and can’t end up or give up I know there will be lots of consequences to face but I have a hope that may be my father accept it

After my mother's death, my father (54 years old) is involved in extra marital affair with an unmarried neighbour girl (25). Nobody knows about their affair except our family. Me (23) & my sister (21) tried our best to make my father understand that this is not the right time to do all these things, but he is not listening to us & not ready to understand. It seems useless for him to have affair with her because there is no future of this relationship. Age gap is also huge. Her parents also don't know about it. Neither we can tell about it to them, because they will target our family & ruin our life. They can also file police complain against our whole family if they gets to know about it. I am sure they will also deny this relationship. Took our relatives help too, but it didn't work. Don't know what to do. Can you please help ??
