DEAR ABBY: My boyfriend and I work out at the same gym. Over the past several months it has gotten back to me that one of the trainers, “Bob,” has been talking negatively about me to some of the other members. My boyfriend works out with another trainer there, and during his workout, I approached him and his trainer and expressed my anger about what Bob was doing. I said I was fed up and that I wanted to confront him. My boyfriend told me to keep my mouth shut and say nothing. He said I shouldn’t take it personally,
