I'm honestly still amazed by this situation and I can't imagine what my grandmother went through. Overall, I thought long and hard about confronting my father's stepmother, but in the long run I knew it would result in more conflict and my family really doesn't need that right now in their lives. So for now I will keep this secret and eventually, when I get older, I will talk to my father's stepmother about it to get her side of the story. As of now I will act like I know nothing and get on with my own
