It's been just over three years since I got married, and I remember thinking (amid the nearly debilitating fear that we would run out of alcohol at our mountain cabin wedding and thus trap our families in a scene from The Shining) that it would be wonderful to finally be free forever from the intrigue and confusion of dating.

You can't fault the optimism.

Now, through the lens of hindsight, I realize that I should have known that dating and even cohabitating were only warm-ups for the big dance.

Example: I didn't really mind the eggshell color of our living room walls——it provided a functional backdrop to both the climbing/skiing pictures taken by a friend in Patagonia, and to the portraits of Italian cafes and riverboats Kristi's father painted, which we hang in place of the climbing photos whenever he visits.

However, to Kristi, the color was "dead guy white." Let me also explain that we have rather complex crown moulding framing the stuccoed ceiling, making painting nearly akin in needed time and expertise to completing a PhD in particle physics. She wanted something "bright and cheerful, like a nice sunshine-pumpkin. Oh and blue trim."

I really had no idea what I wanted other than not to paint the living room sunshine-pumpkin with blue trim. Needless to say:

And I should have known from the start. Why, I wonder, didn't I realize sooner the way the wind was blowing and just paint the darn thing, rather than creating relationship strife to the tune of then also needing to put a skylight in the upstairs bedroom?

I needed an equation—something along the lines of "Is she really serious about that home improvement project?"

I thought, though, that before getting to this one, I would look at some more fundamental equations that govern marriage.

In the equations below, the first is based on solid statistics — an 11,000-person study by the CDC that explored factors that help and hurt a marriage's chances of working (for example, they found that if a woman is married before age 24, her chances of staying married for 15 years decreased by 30%).

These statistics were easy to write in math terms, and the equation does fairly accurately predict your chances of being married at time "T".

Granted there are other factors that might help or hurt your specific marriage, but the CDC study found that, for most people, these are the biggest factors. Remember that the average for all marriages is only about 50% and if you get a low number, please accept my very best wishes in bucking the odds.

The other two ("Should we get married?" and "How many kids should we have?") are a bit more shoot-from-the-hip. With this kind of equation, I try to make the math match common sense. If you put in honest numbers, they return honest answers, but they're not quite as scientific as the first.

So, good luck, have fun, and check out posts deeper in the blog for additional marriage-relevant equations.
