My father is dead but I cut off contact with my step mother. I did try to understand her but it got to the point where I decided I couldn't have her in my life anymore. She has made no attempt to get in touch since which actually underlines our whole relationship, ie, she never tried to close the gap. It's hard, I don't do this easy, I miss the tiny part of her that I loved. But ll her other parts were to destructive to me. I don't feel I have to forgive her, she did what she did, I just have to concentrate on my life now.
