Dear Amy: My wife is an avid runner and usually runs on the weekends with a group of regulars. Recently a man entered the group, and he seems to be reaching out to her a lot. This started with questions about running, but seems to have morphed into other areas. He always initiates texts, and she responds politely by answering his questions. She is completely open, shows me everything, and often brings up to him that she has plans with her husband and kids.
