Well, I didn't want them to think I was doing to spite my father. Since my dad and I never got a long, and I never truly knew him, compared my other half-siblings on his side of the family. Mainly because my mum and sisters never had a good word to say about him while I was growing up, given how abusive he was towards our mum. Though, thankful that was long before I came into the world.
And when he did come back into my life, my mum and sisters just expected me to forget the story they'd told about him. And my mum's relationship advice to me, which was obviously heavily influenced by her past relationships. Particularly with my dad, and the relationship previous to that, my older half-sister's dad.
