I don't get this question often from older folks (i.e. past their mid-twenties usually), but once in a while I get a dating question from a gent in his early 30's who wants to be sure he's in love.
In a way, I understand the confusion. It is much more common now for singles not to pursue (or even want) a serious relationship until they've navigated their 20's; just look at the marriage statistics from the U.S. and Canada lately - although this may have to do more with cohabitation being the norm than anything. Still, I've met more than a handful of men in their 30's over the past couple of years who have readily admitted they've never been in love or "didn't know" if they'd ever been in love.
Is it that true love is more elusive these days than in yesteryear? Or maybe love is in part, hindsight; we think we're in love, but when the ensuing breakup occurs, we realize it was more lust or infatuation than anything else.
How do you know when you're in love? What are your indicators?
