"with 8 billion other people in the world, who's to say we're soulmates?"
Flip that around. Who is to say you are NOT soulmates?
If he thinks long term partners are just out there to be found ... he's a fool.
I like the article, "Why You Will Marry the Wrong Person" by Alain de Botton, published in the New York Times. I can't link it here, but if you Google the title, it comes up first. It's all about why there is no perfect partner out there. I mean, there is, for the first 3 years when you're infatuated....
