My heart goes out to you and your family. I had tears in my eyes as I read your post. Family is what it is. Parents will make mistakes, some more damaging than others but in the end love is truly what matters.
I am so glad that you were able to forgive and bring peace to yourself. Your Dad knew that and I am sure that helped ease his guilt somewhat. He held onto it himself as a reminder of the harm he had done. You couldn't have changed that.
I believe we carry those things with us througout our lives to not repeat the same mistakes. Look at your own life and see if that isn't true. Make peace with yourself as you go. Forgiving others may be easy at times but forgiving yourself may be the hardest thing of all.
hugs and blessing. kat
