From my personal experience. No parent.
I've told the story of my father before. Dude was a shitty parent. He had 4 kids. 2 boys. 2 girls.
He had my brother early and never lived with him.
Got married, had my two sisters. Lived with them.
Fucked around and made me on the side, never lived with me.
Out of the 4 kids we can all say the two boys are more mentally stable than the two girls. We all recognize that while it hurt the boys to not have him, it destroyed the girls having him.
Like it really hurts me sometimes to my core how broken they are cuz of the mind fuck he put them on. They try, but they just not right.
And I blame dude
