Soul mates. True love. Is it a thing?
See definitions:
Soul Mates
True love
noun
1.
a person with whom one has a strong affinity, shared values and tastes, and often a romantic bond:
I married my soul mate; you don't get much luckier than that.
noun
1.
a sweetheart; a truly loving or loved person.
But I don't really believe in destiny or that each person has one true "soul mate" or "true love" somewhere out there in the world waiting to be found.
I would agree with the proviso that I think it's perhaps true for some people but not for everyone. I'm quite certain it is not true for me. (Indeed, being alone seems all but a certainty, but I've made my peace with that.)

From the definition of soul make I know which is "unique" :No there is not such a thing as soul mate. There is usually a huge numbers of SO which would be good or you, after all we have 7 billion + people on earth.
But otherwise for the definition without unique : "a person with whom one has a strong affinity, shared values and tastes, and often a romantic bond" what is the difference with simply being in love ? That definition is as generic as heck.
I vote no on principle that soul mate as defined by the op is generic and meanignless
Hilighted: That's not the definition given in the OP.
So far the results are leaning towards no.
A while back I asked the light of my life this question, and he answered with this.
I can't view the video at the moment. Is it Tim Minchin?
Soul mates? True love? Absolutely.
But, the idea that there is or can be only one? Ridiculous. I've had a few so far.
I have an unrequited love. So does my wife.
Anyway, I don't know the answer to your question. From a purely biological standpoint, I'd say no. However, there's a bit of poet left in me (from lunch) that hopes the answer is otherwise.
From an evolutionary perspective, love is a trick the mind plays to keep the body from taking of for Vegas.
I'm surprised at the number of cynics who say there's no such thing....
So far the results are leaning towards no.
As an atheist I neither perceive nor accept any "purpose" to the similarities beyond evolutionary drives and general population trends; nor any sort of cosmic fate or destiny behind them.
