My mother and father were married when I was born. For reasons I still do not know to this day, she abandoned both of us when I was about 10 months old. So even though I was not adopted nor the child in a same-sex relationship, I can fully attest to the lifelong hurt, lifelong yearning, and lifelong anger that comes with not knowing both one’s mother and father. Nothing and no one can answer the questions a child has about what amounts to a non-existent parent.
You reminded me of something...
Using DNA adult illegitimate children are connecting to their birth fathers and half siblings...
What happens when this child finds his or hers years later ???
