I don't care about my dad
Is there a reason why you don't care about him?
I don't see the need for spending time with him.
Not everyone in a family will always get along. Just because they are your family doesn't mean that you need to get along with them.
I don't get along with him. I do not care about him, he's not a good person. I just want to get money from him.
It is okay to not get along with your father but if you ask him for money, he will continue to be in  your life. It would be good to cut ties completely if you don't want him in your life.
