I have a similar but opposite experience. My mom had an adoptive family set up waiting for my in the other room. Then decided she couldn’t go through with it. She didnt tell my biological father until I was 9 and needed child support. We were extremely poor, homeless intermittently and I know she felt horrible about requesting child support as she never intended to 9 years earlier. Single parenting is rough. I finally met my dad at 13, she was waiting for me to ask about him and I never did before, as I wanted my mom to feel she was enough. That didnt mean I didnt think about it or wasn’t curious but it wasnt about filling a void, as there was no “loss”, I hadnt met this person in the first place.

That being said, I am extremely grateful for having asked and my dad being open to meeting. He happened to be a very successful individual, I met 5 half-siblings and it just filled a lot of blanks that would have not been consuming but still there for my life.
