Regardless of what many comments say, your feelings are completely valid. I’d be upset too. It’s not like your dad is doing anything monstrous, but it’s plain stupid (to say the least). Sometimes, love is that way. It lasts whatever is needed for the people involved to learn some stuff.
Be patient. Your support will be needed, sooner or later. Even if the relationship doesn’t end at all. There will be drawbacks. If you don’t feel up to the ‘task’, cool. It’s not an obligation. Just keep your distance from it.
Btw, 19 is a good age to start living with some frens. Perhaps a talk with your Dad is due… do not make it about this situation (or not exclusively). You deserve your own space. I believe the need for it can be something that was already in the works, and now you are getting ‘hit’ by everything altogether and all at once with this situation.
Good luck!
same happened with anarchism. I bet someone will come reply to me, saying that anarchism is actually bad because it means “chaos” and “no laws”, yada yada.
