I didn't meet my biodad until I was 14. We saw each other maybe 2 times after that. I didn't have any contact with him until last year. We reconnected on Facebook, but he seems to think there is more to our relationship than there really is. I don't know him. I don't know any of the other members of his side of the family. I'm supposed to be familiar with a whole family of half sisters and aunts.
Now he wants to talk on the phone. I am not comfortable with this. We have exchanged numbers, I just don't like talking on the phone, to anyone. How do I tell him this without saying, sorry but you're a total stranger to me?
