Attractive co-worker asks me to have dinner with her (yes, I'm married). She said to bring my wife and she would bring husband. That way she said its just having dinner and not just a romantic escapade.

I made up the story that my wife feels uncomfortable because my intuition said that there was something fishy.

I told my friend what happenned and said to him that my I should change my mind and take the offer because my wife and her husband would be right there, that there is no fishy business.

He said I was naive and girls do tricks like that to get guy at the end. But that's crazy, who is crazy enough to do something like that?
