Him: You have no idea how much changed...like, after you left.
Me: Well, yeah, we broke up right after college - everyone changes after college. I wouldn't expect everyone to be the same person. We all grew up.
Him (laughing): I don't know if I would say that. I wouldn't say all of us "grew up."
Me: Okay, we all got older.
Him: Yup, that's what happened. We just got older.
