Although I was not included in the sample when this survey was taken, I was a never-married single between 20 and 29 at the time. Had I been asked, I would have been in a miniscule minority (6%) that did not endorse the statement: "When you marry, you want your spouse to be your soul mate, first and foremost."
What exactly they meant by "soul mate" is unclear, since it apparently has nothing to do with the person's religious beliefs (only 42% thought those matter) and sexual activity is by no means reserved for such persons. Apparently it's just one of those things you know when you see it, an emotional connection divorced from the spirit or body.
Meanwhile, my young, cynical self was keeping an eye out for someone with similar religious beliefs and lifestyle preferences, someone capable of intelligent conversation and laughing at a good joke. Someone who could be a good friend and a good father. That narrowed the field down amply; insisting on a deep, mystical connection just seemed like it lowered the odds too far. Alas, I did not share the unshakable faith of over 80% that there must be One Right Person out there and that I would find him when I was ready.
What I did find was DOB, a good friend with a similar background, who was willing to marry me. So we proceeded forward, with little concern over whether we were truly "soul mates" or not. As it turned out, when you spend a lot of time around a good friend who gets your jokes and shares your deepest beliefs, who also happens to be a reasonably attractive member of the opposite sex, feeling a deep connection often just happens anyway.
And it takes time to find out things. Many areas of deep connection we didn't even realize until we'd been married a while. Other things we thought we had in common have been dropped on one or both sides. Some areas we'll never fully connect on: I'm never going to love baseball that much, and he's never going to be that thrilled about Shakespeare. But we'll still watch ball games and Shakespeare together. We read different books, but we talk about them together.
A feeling of deep, mystical connection can happen. But it's an awfully flimsy thing. A few sleepless nights, a misunderstanding in a stressful situation, or just the difficulties of profound conversation in a house with children can leave a couple feeling, well, not so soul-matey. But we'll still be living in the same house, paying the same bills, raising the same children, and sitting in the same pew (until the next potty run or tantrum, at least)--sooner or later, we'll make time to connect again. Being soul mates is wonderful, but being able to count on each other is so much better.
