I think one of the reasons people use the word love so carelessly is because of how our culture portrays it in books and movies. Love is described more as a simple feeling that can come and go and has no real meaning behind it. You see so many examples in books and on television of married couples having affairs with each other but constantly expressing their love for each other. It makes no sense to the true meaning of love and simply shows the audience that love really doesn't have much meaning behind it
