So many generalisations and a complete lack of understanding of there being other valid ways of conducting a relationship beyond what you’ve experienced yourself or seen with your own eyes.

True love is like any other feature of a relationship, only as enduring as the health of that relationship. That takes work, communication, and many other aspects too numerous to list here. It is complex and not easy to define. But it can endure just fine.

If it makes you feel better to think that relationships based on true love don’t last, by all means continue in that fantasy. But it is a fantasy and I think it says more about your fear of what you’re missing as someone who’s likely stuck in an arranged relationship, or stuck in a culture where that is expected of you, than it does about how enduring true love can be.
