Thanks for sharing, its weird when you put it down on "paper". It is hard to hear from other bdads. I myself am a bdad, my story isn't anything like yours. My daughter knows, I know, her mother and family know, but only she knows when she'll want to talk, could be right now....nope, maybe tomorrow, next week, next month, my 40th bday, christmas, next year, never...who knows. She has all of my information, and a good photo collection of me "growing up". She'll get it. Your daughter, who knows? I think everybody has a time when even the family they know is unbearable, or "can't be bothered". For me to some extent, I feel that emotionally I wasn't prepared for this before, now I can take this on, it's tough, but I can manage.
That is so freaky, about you running into her! Also makes me think of my missadventures from 1988-1993. I don't have a sence of any other children, but then again, I am not as "tapped" into myself that deeply...still addresing some childhood abuse.
I'd keep looking, and do all you can to "stalk" the one who you think is yours.
Depends on the age of your daughter...as I am finding out
