DEAR ABBY: Thirty-two years ago I was seeing two different men. I slept with each of them in the same week and became pregnant. I told them midway through the pregnancy that the baby might be theirs. One ditched me. I never heard from him again. The other is my husband of 31 years. We went on to have two more children. I have suspected all along that my oldest son, “Todd,” wasn’t my husband’s biological child. When Todd was 8, we did a DNA test, and I was right.
