I agree with nicholeflynn. Emotional abusers can't hurt you if you don't give them free rent in your head. Cut all ties, make no excuses. Don't feel bad about returning their letters, etc. There is a extremely ancient story about a wicked man who wanted to be rid of his old dog. H threw the dog into a dry well, and began throwing shovelfuls of dirt into the well. The dog climbed up and up the mounding dirt until he got close enough to the surface, he leaped up out of the well and got away. Well I guess this means never give up, even if someone is trying to bury you. Maybe this is some story your father should hear, or not. When he is older he will or not regret what he has done, it has nothing to do with you...PS I was that Dog once, only still a puppy, but same thing. Good Luck
