Do you couples talk about their ex's often even if the relationship was not positive?

Sometimes I wonder about what couples talk about, mainly anything to do with their previous relationships. I don't have an ex, I was an ex-admirer. I liked this girl in high school and she didn't like me and decided to make it a game to make me feel bad and get the whole school in on the "joke". At the end of Senior Year, I got my "revenge" and made her feel extremely foolish in front of the whole school and she was furious. Now she is getting married, and I DON'T care at all but I am curious from a sociological point of view. Does she discuss me with her fiancée. I personally don't think so as I "won" and she is very prideful so I don't think she wants to talk about a perceived weakness but I could be wrong.  Do you think I was ever a dinner topic?
