I want to open palm slap my dad in the face
Why do you want to hit him?
I cannot take it that he doesn't show any sign of remorse for what he has done
Family members can make us angry but we shouldn't violence is not the answer. There are better ways to resolve an issue that won't hurt the relationship more.
I don't care anymore if it hurts the relationship. My dad needs to see that I'm the person in the family who has to make the big decisions.
I am sorry that you are having trouble with your dad. But striking your dad is wrong. He could attack you back and then both of you could end up seriously hurt.
