This is just somewhat of a random reflection, but have you heard "The Pina Colada" song lately?
Basically, it's not just about someone seeking a companion who likes to drink cocktails that taste like sunscreen and diabetes...it's a cheery tale of thwarted infidelity, and how it brings people together.
There's a guy, our hero, the narrator of the piece. He has a girlfriend - they live together. It seems to be a long-term relationship, but all the verve is gone. Perhaps, even, sexual intimacy is on the wane. There may be other problems, but all our narrator chooses to emphasize is his boredom.
One night, while his girlfriend is asleep in bed next to him, he starts trawling the personals. He reads one ad, promising outdoor sex, syrupy cocktails, and escape - and that's all it takes. Forgetting all about his girlfriend, he writes back. He arranges to meet with this stranger in a local pub, and take off together.
The purported happy ending of the tale is that the woman who walks into the bar is his old, dull girlfriend. Finding out that they were both into alcohol and mild exhibitionism, their relationship is rekindled, despite the fact that they were both prepared to scuttle the entire thing for the first stranger who happened along with a blender and some docksiders.
Somehow, I don't think this is how it would happen in real life. Somehow, I think the real ending to the song would involve "Cheaters"-style screaming and crying, and the sentence "Get out of my sight, you coke-addled whore!"
I suppose, though, "coke-addled whore" probably didn't fit in to the rhyme scheme.
