I guess my question is why do you feel the need to bring it up. If it is still an issue for you, then yes, that seems like something you probably would want to share. If you've moved past it and/or don't feel like dredging it up serves YOU, then don't. We don't have to necessarily share everything about our past with everyone new in our life. But you really have to know if talking about it serves YOU and YOUR recovery or not.
