DEAR ABBY: I caught my husband talking on the phone to another woman. I heard him say, “Get some sleep, sweetheart,” and “Thank you for being my companion.” When I called him on it, he claimed nothing was happening and he had used the wrong words.

Dear Abby is written by Abigail Van Buren, also known as Jeanne Phillips, and was founded by her mother, Pauline Phillips. Contact Dear Abby at www.DearAbby.com or P.O. Box 69440, Los Angeles, CA 90069.

I’m hoping that you can help me. My sister and I are distanced from each other. We haven’t spoken since the passing of our mother three years ago. Today I learned that she has been diagnosed with stage-3 cancer.
