My uninformed suggestion is that first thing, you get a Caller-ID so you know when he's calling--and let him leave messeges, but only call back if you
know you'll get the answering machine. After that, maybe find yourself a safe place to stay for a while, where your Dad won't think to look for you. Have someone pick up you mail for you, and pass it through a pre-arraged system of people you trust, so that he can't follow it to you. BE CAREFUL! I don't know you, but your dad sounds dangerous! You may need to run for you life if you're not careful!
It sounds like you have a lot to deal with, and personally I think you do need to deal with it. Maybe not talking to him, maybe writing him, but absolutely not going to see him! and if you think you might not be able to handle it when you're alone and have been thinking about it for a while, then you most certainly won't be able to handle it when you're actually talking to the guy. We almost always think ourselves better prepared than we are, until we begin the test-so to speak.
You don't owe him anything, remember that. You are your own person, you absolutely have the right to not wish to talk to/see/hear from your Dad.
If he persists in hassling you, I would try to get proof of it--tape recording or video, phone records, answering machine records, I dunno. Then get an order of protection/restraining--it's much easier to get one nowadays if you have proof of current hassling or physical abuse. Many judges will throw you out on your tail unless you have solid proof of one of these things.
I truely think you need to deal with this issue on your own--you may never be able to face down your Dad, and that's OK. You shouldn't have to. Not that I'm in a place to advise, really-but hey, if this helps I'm glad to assist.
Will be praying for you, that God gives you wisdom, strength, and peace of mind.
