Do they make sense? That’s a subjective question.
When many people hear/read stories of first love…they can relate to the intense sentiments that they may have once experienced themselves…or may even be going through. In hindsight (after gaining more experiences as you go through life)…your perspectives about those feelings may change…as your definition and understanding of love and relationships develops.
There are some people…who meet…fall head over heels in love…get married…and have a successful marriage. They may not perceive their experience as “crazy.” Just because one didn’t fall in strongly in love before marriage…doesn’t necessarily mean that they’ll have a successful marriage. And there can be many reasons why two people who fell in love don’t end up getting married…and don’t end up living happily ever after…doesn’t necessarily mean that they’re “crazy.”
Also, what’s considered as “love” to one person…may be considered nothing but an “infatuation” by another. Love is a strong emotion…just like hate.
It can be crazy, fun, and bittersweet…before marriage…and after it as well.
