DEAR ABBY: I have been happily married to my darling husband for 20 years. The problem is his sister. When we first met, she asked my husband if I was “for real” because I’m very outgoing and affectionate. In the early years, and until about six years ago, she would berate me with abusive criticism. In most instances, her comments were inaccurate. If I tried to overlook her actions and have a good relationship, she would soon find something else to criticize. I am normally an “it’s history” kind of person when it comes to confrontations and forget them quickly.
