Should I tell friend’s son that I know who his real birth father is?

DEAR ABBY: Forty years ago, a neighborhood boy fathered a child with a neighborhood girl. “Billy” was 17 at the time, and “Becky” was 14 or 15. Both were friends of mine. They were not a steady couple. She liked him, but I feel he used her. I heard that she married an older gentleman who accepted the baby, “Matt,” as his own.

Ten years ago, I found Matt on Facebook. I told him I knew his mother, and he shared her contact information with me. When I called Becky, we enjoyed talking about old times, and I let her know that Billy had passed away. She informed me that her husband had also passed away.

I was surprised when she told me she never told Matt who his biological father was. He was raised believing his biological father was Becky’s husband. I have photographs of Billy, and Matt has an aunt he is unaware of. As tempted as I am to inform him who his father was, I know that is not the right thing to do.

We don’t communicate regularly, but Becky and I are friends on Facebook. I believe she’s having health issues now. Abby, If she passes away, do you think I should let Matt know who his father was, share the photographs and let him know about his aunt? I think I’d want to know. — OLD FRIEND IN CALIFORNIA
