dead beat dad

I no longer consider (for the sake of the story we'll call him donut) donut my father. I have had a dad since I was 3, and it's not donut. When I was about 5 I was asked if i wanted to go see donut, who is my bio dad, since I had no concept of what kind of person he was I said yes. Though as time went I found out he was a terrible father, he got drunk, woke me up at 4 am, yelled to me about how my family was gonna r4pe me! (they never did) and so much more. Over time I have grown to resent him for it. About 1 yr 1/2 ago he went to jail, not for me or my sister surprisingly, but for my little brother, whom he only had access to every now and again. The time he was gone was the best time of my life! When he finally go out of jail he asked for me to come back to stay with hime partially, like we had before. I said no and explained why, now he's till pressing and evening exaggerating to my family about how I "Neglected him, and said he was a terrible father.", which he is! But I didn't say like that. I was kind and respectful. Now I'm simply sick of it. I have blocked him but he's still in contact with my family. I WILL NOT be going back to him, and to be quite honest, I hope he stays unhappy. Because with all the pain and sadness he's caused me the only thing I wish on him now is for him to suffer alone and think about his actions. Some say I am being to harsh, but I really don't care anymore.
