I still think about someone I liked in high school, even though I’m happily married and wouldn’t change anything about what happened. In fact, I think I’d have more problems if I ended up with that them than my SO.

I think most people have that “one that got away” that they think about, regardless of their current relationship status. And I don’t think it has anything to do with that specific individual, but the circumstances that made them stand out to you at the time, like that favorite video game that doesn’t hold up today but you still want to replay (or maybe have replayed multiple times).
