My father had an affair when I was a child. My mother told me about the affair as they split up for a short period, and it then dawned on me that he had taken me on days out and introduced me to OW whilst the affair was ongoing. My mother got back with him for financial reasons and he was a presence in our home throughout my childhood. I have never forgiven him, even 20 years later I still have a lot of resentment towards him.
Our relationship suffered and we have never been close since that time. I was a very difficult teenager, a massive part of that being because of his affair, and we had a very tumultuous relationship.
Has anyone successfully been able to forgive or move past situations like this? And if so, how?
