I guess it was because I'd heard two or three stories of the woman being seven years older, so I'd sort of decided that was the outer limit of age difference acceptability. (And I would hit 31 a month before his next birthday.) Feeling defeated, I sat at the small wooden table in Starbucks, where I was meeting Kevin for the first time since my startling discovery. In case you're wondering, I married that guy eight months later.
I don't know why this one year made such a difference to me.
Although this is a fun rule of thumb, what does research say about age preferences for potential mates?
There are two things that predict a preferred partner’s age: (a) your age and (b) your biological sex (male vs. From an evolutionary perspective, it makes sense for women to prefer mates with resources and to like partners who are more established, both of which are more likely in older partners. It turns out that, on average, women tend to be married to men a few years older than themselves (2-5 years).
Not everyone will agree with the results of this formula, but it does provide a good starting point, as it keeps younger, less mature people together while giving more of a range for older adults.
