You're not alone in that idea. The ancient Greeks believed that, in the beginning of time, humans were actually one entity with two heads, four arms, four legs, etc. Forces ripped that entity into two, exiled them to opposite ends of the globe, and from that moment, our eternal quest has been to rejoin each other — to find the “other half” that completes us. It’s a pretty romantic concept and probably gave birth to the whole illusory notion of “finding your soulmate.”
That did cross my mind whilst I was writing that, I also don't believe in a "soulmate" in that sense though, but it is a nice story
I do believe in pre-determination, but not that we were once together at an earlier point, or that my partner is the "perfect" partner for me, or that there could be a metric for such a thing (though if there could be, she comes pretty close)
(Incidentally, the source for that story, Plato's Symposium, I decided to read a bit more about it, very interesting, check out the wiki page, Aristophanes says you come from the sun, Rat comes from the earth, and I come from the moon)
