How come you aren't married?

When I was 15 or so, I thought I’d never get married. What did I need approval from the state for? Eventually I decided there were good reasons to get married.

But this is not about reasons to get married. It’s about reasons we tell ourselves we shouldn’t get married, and reasons why we have rejected so many potentially marriageable partners. The linked article is about women, but men might think of their reasons, too.
