DEAR ABBY: My dad carried on a 30-year affair with a married woman I'll call "Lily," until he immigrated to Canada with Mom in 1984. Despite Mom's constant anguish over the affair, she and Dad stayed married for almost 54 years. Mom passed away 19 months ago.
Lily, now widowed, recently moved in with Dad. He is now 79 years old. My siblings and I do not object to his relationship because we want Dad to enjoy the years he has left. However, out of respect for our late mom, we declined his invitation to meet Lily. Dad is disappointed when we tell him that we don't care for Lily's company during our future visits with him.
Abby, Dad's affair left a deep scar on our childhood. Do you think we acted reasonably under the circumstances? -- AT A DISTANCE, ONTARIO, CANADA
DEAR AT A DISTANCE: Your feelings are understandable. However, unless you want to create a breach with your father, you will have to release some of your resentment about his old mistress.
