Do you think your "soul mate" is out there somewhere, that one individual who can complement you and fulfill you like no other? Is there one man or woman who is ideally suited to you? Is it your life’s task to find this mystery person?

Surprisingly, many singles hold to the notion-either consciously or subconsciously-that there is only one perfect, preordained partner for them. They were made for each other, the thinking goes, and they must simply locate this person or forever feel incomplete.

This thinking is fueled by many Hollywood love stories in which a man and woman are united after a series of near misses and obstacles. At long last, they gaze deeply into each other’s eyes and embrace, usually amidst the swell of violins playing in the background or fireworks exploding overhead. And they know without a doubt that they-the two of them and only the two of them-were meant to be together.

For other people, religious faith fosters the one-perfect-person idea. We often hear the cliché, "It was a match made in heaven," implying that God hand-picked a particular man and woman to be joined together. If these two somehow goof and marry someone else, they have missed God’s perfect will.

I admit that this notion of locating just one soul mate is appealingly romantic. We love the quixotic notion that out of the millions of people in the world, my sweetheart and I were drawn together as if by some transcendent or supernatural magnetic force.

But, frankly, I think this idea is more fantasy than reality, more storybook whimsy than real-world wisdom. I don’t believe that you could only be completely and blissfully happy with one person to the exclusion of all others.

Before you call me unromantic and cold-hearted, let me hasten to say this should come as great news to singles looking for a partner. After all, I hear dozens of singles every week complain about how hard it is to find a suitable partner. And if there is just one individual waiting for you out there in the wide world, the search for each other could take a very long time. If, however, there is not a "one and only" partner, a whole range of possibilities opens up.

How did I come to conclude that the lone soul mate scenario is a fallacy? During my thirty-five years as a psychologist, I have counseled dozens of men and women who were convinced they’d married "the wrong person," but who then went on to create top-notch relationships. Of course, I’ve also counseled many engaged or newlywed couples who were absolutely positive they had found their soul mate-only to file for divorce a few months or years later. What’s more, I’ve worked with hundreds of people who I knew could have been happily married to any number of people.
