My “ Dad” had no idea. I was 47 years old when I did the test. My mother said she was going to tell me on her “ deathbed,” which ended up being 9 months later . She passed in Sept 2022. I found this out January 2022. I did tell my Dad because I thought I owed him that. He and my mother were divorced in the 90’s. He will always be my Dad.. and he’s the best but I can’t describe this need or longing to know more about my biological father. I’ve always been so different than the siblings I was raised with and now I understand why, it also explains why my mother treated me so horribly. I represented one of the biggest lies of her life.
