The phrase "truly best for each other" emphasizes the idea that certain individuals are exceptionally well-suited as partners. They share a profound connection and compatibility that makes them a perfect match.
However, the statement also recognizes that this compatibility doesn't always guarantee a smooth path to being together. Instead, it suggests that circumstances, external factors, or personal challenges can create barriers that the individuals must overcome in order to be together.
In essence, this statement celebrates the idea that true love and strong connections are worth fighting for. It acknowledges that facing and overcoming obstacles can ultimately strengthen the bond between two people and make their love even more resilient and enduring.
