Its hard not to think of someone you hate. I hate my father too. Some ways i try to forget him by are getting obsesed with something so much that you can only think of it. When it doesnt work that way, I do more of my hobbies and keep to busy to think about it. Im not brave enough to do this but perhaps you could talk it over with him. Please use the discussion page to keep me in contact because I want to help.
