I had just recently broken up with my long-time girlfriend. My ex, while beautiful, had been clingy and irritating. I was looking for a true FWB type relationship. So, l went to the old reliable craigslist.
I eventually sifted through the spam and trash, and found Carla. Carla seemed to be a rational person with a high sex drive; just what I was looking for. She was married... but, that just added to my excitement. (I tend to find that married women are more stable and predictable than their single counterparts.)
