So basically, my parents are my aunt and uncle and my aunt is my mom. Let me explain. My parents were having trouble having a child and no fertility treatments were working, so then, my aunt(mom) got pregnant and offered for me to be my parents(aunt and uncle)'s child. So fast forward 9 months, I was born. My parents now adopted me the second I was born and took me home from the hospital 4 days later. The thing about this is that I don't know who my biological father is and it drives me insaine. My aunt(mom) died 3 years ago in a car accident, but she was the only one who knew who my biological father is. She didn't tell my parents. She didn't tell her closest friends. She didn't tell anyone. So, to this day, I still have no clue who my actual father is...
Your actual dad is the one that's raised you (your uncle?) the one that's brought you up and clothed you and fed you.
And also, was your aunt/mom a surrogate or the actual egg?
(I think the people that say they're your parents might actually be your parents with the egg and sperm and your aunt may have just carried you? That's usually how surrogacy works)
Also, even if you don't know who provided the sperm, does it really matter? He never intended to raise you, he donated his sperm, and no offence, but he probably wanted to give his sperm not have a child to feed and look after. So again, your father is the one that has raised you, gave you money, fed you, wanted you and raised you.
Finding out which sperm particle you come from, doesn't really change anything about you.
