The monologue that you write after a break up, be it as a dumpee or as the dumper. It self-indulgently describes in great detail the feelings that you have been through before, during, or after the break down of your relationship, or all. This results in many paragraphs of text, often re-written to the quality of a college essay, to eloquently as possible express your thoughts and emotions. This may be written immediately after the break up, to clear the air and begin the healing process, or it may take a while to get straight in your head. It can be written a long time after the break up, as you may not want to look weak by showing that you were still thinking about the relationship, or give off the false impression that you want to get back together.
Though the ex that you send this to may no longer care about your emotions regarding the relationship, by the time you write your Monologue of Moving On you are ready to leave them to their own devices and move on.
