“If you want to believe human beings weren’t built for monogamy, that’s fine, but it’s a small way to look at it. We also weren’t built to eat at tables or work routinely or refine our minds or wear clothes. We do these things to have a higher quality of life. Freedom is not the ability to act on your impulses, it’s the ability to choose what you want to act on. There is something exceptional about having a single romantic relationship for your whole life. On the other side of how difficult it is, it is equally as profound: imagine the kind of love it takes a lifetime to build, the kind of intimacy that blossoms from taking so many years to know a person. But it's not that we’re only meant to have one romantic relationship ever – things can fail despite our best efforts; breakups are often essential to personal development, or even maintaining sanity. The point is that using your nature as an excuse for not being able to commit is weak.”
