I hate my dad, I hate spending time with him. But I can't help wanting to be with him

Being with my dad is awkward; I don't know what to say or do. And it frustrates me that he definitely doesn't care about me enough. I know it's not easy, given everything we've been through, but I can't help feeling a certain resentment. I mean, do you care more about someone else's child than your own daughter?Do you care more about taking that child for a walk, who doesn't even see you, than trying to rebuild the good relationship you had with your daughter? It disappoints me. I'm supposed to know what my dad is like by now, I'm supposed to not be hurt by it anymore, but the way he says things like it's nothing... It's just disappointing.
