Do you stay to long in relationships that are going nowhere? Is your girlfriend, boyfriend or spouse a negative influence in your life? Does he/she treat you badly (we might even ask simply, does he or she treat you in a way you don't prefer to be treated)? Does it seem like you can never quite get on the same sheet of music, so to speak? And to quote the song, "How long has this been going on?"
A long time, right?
Your significant other is not your problem. As with absolutely every aspect of life, if there's a problem, YOU are that problem. In this case, you may suffer from the human addiction.
