Dear Annie: My sister-in-law, “Kay,” was once one of my closest friends. For more than 25 years, we were there for each other through everything: marriages, divorce, raising children, heartbreak, and all the ordinary ups and downs of life. We never had a serious fight, and I truly believed we would always be family in every sense of the word.
Dear Annie: Do we support a relative who treated us poorly but now has cancer?
