I'm sorry all this is happening to you. My sister's father was pretty bad to her, I guess...so my mom and her moved away from him. She never talked to him since (she was really small at the time) she met my dad some time later. My dad has always treated her like a daughter, and if you ask my sister what he fathers name is, she will say my dad's name. She says he is more of a father than her real one...I guess what I'm trying to say is it doesn't really matter about "blood" he is your father. I guess that doesn't help at all...but I hope it gets better for you, I really do.
