Is what I'm doing right...?

I'm a teenager now but when I was 7 my parents divorced. Then when I was 7 and 1/2 my dad had a change into a women. Since I was 7 1/2 I haven't spoken to him and I hate him was what he did. He messed me up and I'm petrified that one of my friends will find out. He recently added my twitter and I saw a photo of him/ her and I freaked out I started crying and I was paranoid that someone would find that he added me. I hate him for ruining my childhood. Is it right to keep ignoring him? I mean I'm not gonna speak to him ever again anyway but what are your views?
