Remember the days when we had to hide the fact that we were "living in sin" from our grandmas? We wonder how she'd feel if she knew we were married, but not living together. They're often called the "living-apart togethers."

According to the Daily Mail, a new survey found a surprising new trend: One in 20 committed couples chooses to live separately. That marks an increase of 40 percent in the last decade. See: Tim Burton and Helena Bonham Carter, who live apart, two kids and 10 years into their relationship.

While young couples choose to live separately to retain their independence, those over 35 are likely to resist cohabiting because they have accumulated too much crap over the years to cram into one place. (This sounds like a metaphor to us.) The study also found that men are more likely to delay moving in than women, and that country folk are less likely to cohabit than city dwellers.

While living apart may cost you more (in addition to paying two rents, couples who commute between homes are apparently three times as likely to be burgled), it sounds like these live-aparters are onto something: a relationship that doesn't involve fighting about whether the toilet seat is up or down. It sounds like pure bliss.
