I dont think that there is simply just 1 person out there for you. I mean if that was the case, its a miracle these people find themselves. Quite the coincidence that a persons true love often lives nearby, or goes to the same work or has a friend overlap.
But saying that, the value in the love that people experience need not be diminished by statistics. Its always struck me as odd that its often implied that in order for love to be 'true' or 'real' it needs to also be a staggering statistical rarity. Looking for your soul mate, it was meant to be, one true love etc, all loaded language that focuses on the rarity of the phenomenon. The truth is, love isnt that rare, and theres a lot of people you could fall in love with depending on time, place and circumstance. But just because thats so, doesnt suddenly make it 'not true love' when it happens.
