Courting...is it a lost art?

Hey I like sex just as much as the next person and I also like getting straight to the point as well, but there's a point where you have to draw the line especially when after sex you start to see this is not the person you thought they were. What's the rush? Have we traded in our common sense for intimacy? We also will be discussing why do some people fall off in a relationship or get too comfortable and stop doing the things they used to do in the beginning?
