How can I make it so I can't be found?

I am cutting my father out of my life for good. It is a long story and I would rather not get into it but I need to “erase” all contact with my dad. Unfortunately, I only know of a few ways I can do this. I will be changing my phone number, last name, blocking all facebook interactions, etc. But I don’t know what else I need to do. Can you please help me and tell me what else I need to do? Or is that about it? I don’t want to be found by him, period. Also, please don’t try to convince me that I am doing the wrong thing- just help me by answering the question. Thanks so much.
