Do you ever get over your first love?

I often read and hear how women and men can't forget their first love since it's very impactful simply because you do all of your firsts with them and it sticks. Even women in their later 50s and 60s talk about their first love fondly and remember their times together, leaving the impression as if none will ever be able surpass that. I wanted to debunk that theory but was pointed out by a friend how even now I seek out the spark/thrill that my first boyfriend gave me and when I don't find it I break up. I on the other hand feel like that might be more because we had an on-off relationship for eight years and never properly broke up so I feel like I never got closure. So did you manage to get over your first love or are they still lingering on your mind?
