I broke up with my ex fiancé almost a month ago now after we were together for 7 years. Earlier today he emailed my best friend asking him to give her a call. She phoned me up, told me about the email and confessed to me that before me and him got together, she had been sleeping with him for a month. She said they both agreed when me and him got together that they wouldn’t tell me. Although I have no romantic feelings towards this man anymore, it’s still hurt me that they both kept it secret for 7 years. Now I feel like I’ve had my best friends sloppy seconds. I feel sick just thinking about it. Should I have had a right to have known from the start?
