Aish.com thinks we’re still single because we have too many options of people to marry. To quote one guy, explaining his breakup to the girl, “You’re everything I want, but I want to see what else is out there.”
Personally, I’ve never felt that way, but I guess it depends on what you call a choice. Technically, anyone physiologically male is a choice for a mate. But once you start shaving narrow strata of acceptability (this level of frumkeit, that type of personality, compatible life goals) the concept of choice becomes incredibly constrained.
So who decides whether a given date falls within your range of “choice”? Beats me.
