Sex & the Single Woman: Missing Element

Months ago, I talked about one of my oldest friends who came to visit me and started hooking up with a guy who lives near me. Hooking up turned into a relationship, and to everyone’s shock, they are still together.

I’ll be brutally honest–no one saw it coming. I think the world was waiting for them to spark and then fizzle out, but the flame is definitely still lit.

What magic element is there is the most random couples that keeps them not only together, but stronger than the rest of us? Is it really just love or is there a missing element that I am just failing to see?
