Divorce is contagious. That's right - when you have a close couple friend split up, it increases your chances of getting a divorce by 75 percent.

Women tell stories; men want answers. Guys get impatient when we drone on forever; we get frustrated when they tune out.

If you had asked me when I was 28 and in my wedding dress if I ever thought I would end up in my forties flipping my husband the bird over potato chips, I'd say you were crazy.

Scientific studies about relationships fascinate me, and I devour them hungrily, especially when they give big, fancy-sounding names to everyday experiences.

One study found that people who smile in childhood photographs are less likely to get a divorce.

As relationships progress, the time you spend smooching diminishes. Where kissing was once an enjoyable entree unto itself, it becomes a mere appetizer couples hasten through on the way to the main course.

Merely watching a romantic comedy causes relationship satisfaction to plummet. Apparently, the bitter realization that maybe it could happen to us, but it obviously hasn't and it probably never will, makes our lives seem unbearably grim in comparison.
