Guess I'll give it a try too. I apologize for eventual mistakes, as English isn't my main language (French is)
First, a bit of backstory. Since I was born, my father seemed to hate me. He wasn't there at my birth, he never gave me gifts (while he doted my older brother twofold), he always insulted me for weeks at the slightest mistake, and made of my childhood a living hell. Things changed when I was fifteen, and when it was revealed that my father cheated on my mother with one of my brother's teachers (a childhood love of his). My mother asked him to choose between his family or his childhood love, and he chose the latest option. When he turned on us - his three children, me being the middle one and the least loved - to get some support, my only answer was "Why do you ask me some support, while you never showed me love ?". He left right after that.
I then quickly became the man of the family. My mother started to show signs of alcoolism (due to her not finding another man, and the fact she had to throw my brother out of the house for theft of her credit card, for 300+ €), and as she was allergic to alcohol, her health quickly became the main subject. She then suffered from blood poisoning, to make matters all the worse, and as my sister was only 5 years old and I was the only one able to do something, I dropped school to take care of my family and the school. It lasted three years until blood poisoning took the last of my mother, leaving me and my sister by themselves.
Being the only direct parent available, the choice was to stay alone or to live with my father. As I still had problems with my father, I chose to live alone... To suffer the problems that plague everyone who wants to live alone : Finding a new home, trying to get a job, trying to catch back the school years I skipped... Add to that the fact my sister wasn't happy at all with my father, as he spent his live dragging her to bars and drinking up to 3 am, when she had school starting at 7 am, and her school didn't want to do anything as, if my sister went to the next relative (my grandparents) available, she'd surely leave that school due to her living way too far from it. It quickly became a uphill battle between me and my grandparents on one side, and my father on the other.
We won that battle after three long years. A battle that stripped my father of his parental rights concerning her daughter, and said daughter didn't hesitate a single second to spit whatever she had on her heart to my father, which quickly broke him. He then spent the next years going from one woman to another, not caring at all about himself and doing his best to make himself suffer, like it was a normal thing. When I met him two years ago, I hardly recognized him, due to how he seemed aged and in constant pain. We had a talk together and he apologized about all he did to me during my childhood. I saw him cry for the first time at that moment.
We spent that year rebuilding a father-and-son relationship. I acknowledge his faults and he accepts mine. He takes interest in what my life is becoming and wants to give me some help, while I try to take care of him as much as he lets me to. And while I can't forgive him for some things, like what he forced my sister to endure, I can now accept the fact he is my father and I am his son. And the moment I noticed that was the happiest moment of that year.
