A person should never be considered as an option because people are not objects that you choose from. As human, we have emotions and feelings for each other and that should be the only basis for our connection with someone.
At times, people forget the very essence of human relationship. They keep some people in limbo, neither they let go of them, nor they keep them close enough. They think that if they don't find anyone else or a better person, they will choose that person that they have kept as an option. They forget that although people who love you, wait for you but no one wants to be a second choice. For a person who loves you truly, also wants to be loved fairly.
Never take advantage of those who love you. Don't keep them aside like an option just because you know they feel strongly for you. Be transparent in your relationships. Be with them completely or leave them fully. Don't waste the time of their life and yours. Remember, if you want someone to be in your life, don't make them an option.Options don't last. Make them a prioroty, they will be with you forever.
