Why do people lose interest in one another after a certain amount of time

episode number one kind of topsy-turvy this morning having a cocktail talking about my real life situation why did my dude lose interest was it purely because it was only sexual or was it because something I did check me out and see what I have to say you might have a laugh you might get some knowledge might hear something that you were before something you never heard it all as I stated this is my first episode I'm a little nervous so I had to have a cop to enjoy
