None of my parent reported chronic abuse beyond occasional physical punishment (which I don't think it is right, anyway). My grandfather (mother's father) sometimes drank but he wasn't an alcoholic. Probably both suffered from emotional neglect. They claimed to love their parent and were proud of how they were educated.

I preferred to be with my father's parents rather that being with him.

My mother hated me for some reason. She knew what she did was too extreme and wrong so she tried to hide what she did to me.

I don't find an explanation of their abusive behavior towards me, I just could understand emotional detachment or neglect.
