I found an article, "Pain of Unrequited Love Afflicts the Rejecter, Too." There are two sides of unrequited love,
first would be "the would - be lover" and "the rejecter"
both sides shows pain surprisingly, the rejecter often suffers just as much as
the rejected. Why? For me it's a risk to take so that you can tell your
feelings to the person you like or love. Risks that cannot be undone, like
risking your friendship for you to tell what you feel about him/her and You
feel guilty because you'll hurt his/her feelings.
In another article entitled "Unrequited Love: Crushin' On or Crushed By You?" by Dr. Helen Lee Lin. It was said that admitting romantic feelings would change things between the pursuer and the rejector. Researchers made a study on who had either rejected a friend romantically (rejectors) or who had been rejected by a friend (pursuer). The study showed that the long-term friendship would still be friends after one confessed to him or her, the short-term relationships ended their friendship after an unrequited confession.
"possibility of losing a good friendship, the sting of rejection may be more acute when coming from someone close to us." says Dr.Helen. When you are confessing to a friend that you like him or her, You should always think that you are taking your friendship at risk. Well, if he or she feels the same way about you, good for you! but, if he or she doesn't feel the same way. Always think that someone is there for you. And I think that you should still continue your friendship.
Don't stress yourself just because you've been rejected, enjoy your life. You'll still meet other people besides him or her/ For now, be a better person for yourself. Take care of yourself, and Love yourself, then you'll meet the person that you deserve in the near future.
