DEAR ABBY: In my junior year of high school, my girlfriend got pregnant. We married and had a son.
Although our marriage was very rocky, two years later we had a daughter. I knew from the beginning she was not my biological child because of her her blood type her, but I loved her all the same.
Four years after her birth we divorced, and I retained custody of the two children. I later remarried and had one more child.
I never told my daughter or my ex-wife (now deceased) what I knew.
Fifty years have now passed. With DNA testing being so prevalent, I’m at a loss.
