That makes me so angry. I hope you have got the best of revenges - a family of your own who you treat well.My adoptive mother tried to drown me as a child so no they weren’t all amazing mate.
I’m glad many were and I really do understand the OP’s feel for closure.
I found both my birth father and mother fairly easily the old man told me to F off and don’t bother asking for any money his first words to me. His poor wife apologised he was clearly an utter ****.
My birth mother was now a well to do sort fair play to her I guess from living in a bedsit with her family in Shoreham with only the gas stove for heat (another story) she also didn’t want to know.
The way I see it now we are strangers with nothing in common, I often dreamt as a kid how wonderful they must be and how exciting my life would be once I’d found them.
Nope both arseholes who wouldn’t give me 5 minutes.
My only advice would be the vision you have in your head could be very far from the reality when you go searching.
