She framed the story as a “young and dumb” college experience, something she looks back on with humor and perspective, rather than a reflection of who she is today. People in their 40s, especially those who have had mature relationships and are open about their pasts, often share college escapades more as anecdotes than as indicators of current behavior. A single impulsive act from decades ago doesn’t predict that she would act that way in a committed relationship now, particularly if she has demonstrated honesty, openness, and stability since then.
The fact that she was serious in that past relationship doesn’t necessarily reflect on her character today; many people make mistakes even in relationships they value deeply. Thrill-seeking or “naughty” behavior in youth is usually about experimentation and testing boundaries rather than a lifelong pattern. If she’s otherwise transparent, committed, and respectful in your relationship, it’s more likely that the college story is just a story a window into her past, not a warning sign for your present. You can allow yourself to enjoy the trust and connection you have now, rather than projecting old behavior into your current relationship.
