Playing Second Fiddle

Now why is at that women and men are willing to play second to keep someone in their life? What can make a person's self esteem so low that they are willing to settle? Most believe they will have the power to persuade the person to leave there current mate. But until that happens they are content with the little they get or small moments of attention. Most will say the sex is great, they give me money or I know he or she really loves me to keep them there. You have to make yourself a priority not someone's second choice or option. Small food for thought I don't have all the answers or no the only way but just like to share my view.
