I haven't spoken to my dad in 5 years and couldn't be happier.
When I fell pregnant with DD1 he called me alot of abusive names and disowned me.
So I have chosen to never bother trying with him nor with his side of the family. They are all nasty people.
But the nurve of the guy told my sister he wishes to be known as Pop. Well as far as I am concerned he has no right to want to be known as anything. And to this day my girls don't know him, never met him, seen a photo of him and unless they accidently come across anything to do with him will not know of his existance on this earth.
