I am a 44-year-old adoptee who found my birth parents this year. My birth father had listed himself in a mutual consent registry in California 15 years ago, but I didn't find out until I spent a year getting my non-identifying information. He stayed with his teenage girlfriend while she was pregnant with me, and when he married (someone else), he told his wife he had a child who might show up one day. Through him I was able to meet my mother, and that is going well.
My birth father and I had a warm and emotional first meeting in a local park, and met there again two weeks later with my two-year-old daughter. He did not invite me to meet his family, he said, because of upcoming surgery.
