My mom was married to the sperm donor who left when he found out she was pregnant. My dad married my mom and adopted me when I was a few years old. I was told when I was in my 20's. I cried that my dad loved us so much that he wanted both of us.

I know the name of the sperm donor, but he doesn't show up on the internet. His brother knows about me b/c he was my godfather and I saw him a few times in my life, the last time was when I was 13yo, but he's known how to get in contact w/my mom, if he or sperm donor wanted to. Godfather and family are on the internet, but I have no need to make contact. I'm content w/my very small family.
