I broke up with my ex-gf about two months ago. I still see her from time to time, because she works on the block where I live, it's sort of unavoidable. In addition, the place where she works is Subway, and I love their food. We're on fairly amiable terms, but I went in recently and she started spouting personal details about our sex lives to her coworkers. She would say things like "This is my ex-bf, he's great in bed." Now, I realize that what she said certainly isn't negative, but I don't like my personal life being spouted off to people I've never met. I don't mind in this setting because noone actually knows who I am or where I live, but what should I do about this?
