I want to move in with my dad
Can I ask you why you want to move in with your dad?
I know my family will miss me if I move in with my dad, but that does not matter to me.
While it is understandable if you want to move in with a parent, it's not okay to do so if your actions cause difficulties for the rest of your family. You should try to find a compromise about your living arrangements that can satisfy everyone and not just benefit you.
Everything will be fine as long as I get what I want.
Just because you got what you want doesn't mean everyone will be happy. Have you ever thought about how such a change in living arrangements may impact the rest of your family? You should take their feelings into consideration before making such a big decision.
