Dear Abby: Should I tell my child that they’re not actually mine?

Dear Abby: Should I tell my child that they’re not actually mine?

DEAR ABBY: I am a retired Marine who married my supervisor’s daughter. I’ll call her “Zoe.” He and I were good friends. Zoe and I divorced in 1997. During the marriage, I found out that he was not her real father. It was a family secret that accidentally got out.
