It's a ridiculous ideal that someone trumped up because it sounds "romantic".
Even if you do follow spirituality - you have to admit that your vibration is constantly changing and shifting... and the people that you attract to yourself are ebbing and flowing, too.
How can you really expect one person to remain constantly at the same vibration level as you are emitting when you don't remain static from day to day.
@HootyTheNightOwl I definitely agree that people don’t remain constant because that will go against our nature as humans to evolve but I always thought the idea of soulmate is that you find “your person” that your “soul” was longing for and that you’re willing to go through the ebbs n flow in life with not that you necessarily stay constant. But thanks for sharing your thoughts.
