My father was an abusive bullying pompous ignorant monster, and i always said i would never hbave children, because I woldn't want a child to hate me the way I hated him.
My wife had two girsl from her first marriage, aged six and four, and when we were going out, i found myself doing the opposite to my dad as often as possible. I was, and am, endlessly patient, I constantly affirm them as wonderful people, tell them how much i love them, and how valuable they are to us, and as individuals. The same occured when we had our third daughter.
They are thirty-two, thirty, and eighteen now, and have all grown into wonderful women of whom I am totally proud, and most importantly - we enjoy being together, something i never had with my dad.
Yes, the circle can be broken - just be the parent you want to be, the rest falls nto place.
