Dear Steve and Shirley, I am a very happily married woman in my early 50s and I have an issue with my husband’s long-time friend and fraternity brother. My husband’s friend lives in another state for work, but he loves to come visit all his buddies in the city that my husband and I live in. When he comes to town, he would take turns staying at different friends’ houses. His first visit to our new home was earlier this year and he stayed the entire weekend and that was okay, as a one-time deal..........
