My husband went away with work for a few weeks a while ago. He backed up his photos to my drive recently and when I was looking for something else I saw a photo he had taken of his female colleague in a bikini on the beach. Not a group shot, just her posing for the photo. He, and we, were going through a difficult patch when this happened. Would you be suspicious? Or is this normal behaviour if you are away together for a few weeks at a location with a beach?
