I realize I want nothing to do with my dad
Is something wrong with your dad?
He's boring and he also judges me for my hard work.
Not all families will get along, but for such small reasons that is very unfair to your father. You shouldn't abandon him because you think he is boring, he is your father. You need to just understand him a little better.
I've tried to understand him but he is so difficult. I'm not sure how to deal with it other than let him live his own life away from me.
Well, this happens and all I can say is that you can limit being around him. But overall, still stay together at difficult times at least. This will make sure he understands there are boundaries you need to have too.
