Taylor Swift was absolutely devastated when she would go on to learn that her ex-boyfriend, John Mayer, was no longer interested in her, resulting in a bitter breakup. There were rumors going around at the time that the reason why John split up with Taylor was simply down to the supposed fact that he saw her more as a friend than someone he could sleep next to. Taylor didn’t find it flattering to hear that about her, hence why she went on to write somewhat of a payback song against the singer, titled Dear John.
