Dear Abby: I recently found out who my biological father is/was. Apparently, my mother and this man had an affair more than 50 years ago. There’s only speculation as to why.
What bothers me is, I have always lived no more than 15 miles from this man and his family. I tried reaching out to the one half-sibling I am most knowledgeable about. They have made no attempt to contact me about this elephant in the room. I don’t know if it’s shame or embarrassment on their part.
