Is it ok to not to consider my dad as a father?

Well heres the background:/ my dad is ill tempered and has strong personality. He can be very two faced and treated my mom like dirt. My big sister is underdeveloped mental so my dad doesn't give her the attention she deserves and my big sis talks back to him since she's basically a failer since she's trying to be a lawyer instead of a doctor. He was a great father in my childhood but he slowly was becoming less fatherly as a i grew up. He become cheap and stingy with us even though he would give our cousins 2000 dollar cameras, iphones etc. And all we ever got it 5 dollar burgers from burger king. Hes been trying to get close to me after my mom and him divorced but i can't hate or love him i just feel nuetral like i hve no feelings towards him. Its honestly sufficating to be with him when its his turn to live with him. I honestly feel like i have no right to love him because i feel like i stole his love from my sisters. I just feel disgusting like i don't deserve it. I'm angry for what he did to my sisters and mom and it hurts to be with him sometimes. My friends all say i should hve a relationship with him since hes my only father but i'm just so confused like it doesn't feel right to but i feel obligated… Like i have to or i'm being ungrateful.

White dots on iPhone X front facing camera?

I accidentally dropped something on my new X and now I'm paranoid about these two small white dots on my front camera? They don't show up when I take a picture, they're on th actual front camera itself. Is this normal?
