According to another great theoretical experiment from XKCD, the odds of finding your one true soul mate are pretty dismal:
We’ll assume your soul mate is set at birth. You know nothing about who or where they are, but—as in the romantic cliché—you’ll recognize each other the moment your eyes meet. … The number of strangers we make eye contact with each day is hard to estimate. It can vary from almost none (shut-ins or people in small towns) to many thousands (a police officer in Times Square). Let’s suppose you lock eyes with an average of a few dozen new strangers each day. (I’m pretty introverted, so for me that’s definitely a generous estimate.) If 10% of them are close to your age, that’s around 50,000 people in a lifetime. Given that you have 500,000,000 potential soul mates, it means you’ll only find true love in one lifetime out of ten thousand.
