What is it?

Have you ever fallen in love but don't know if the other person feels the same?
Well probably you have and as the days go by the boy or girl makes you feel more in love and start wondering What if? What if you were together? What if he actually likes you? As the days go by you find out the boy or girl likes you. You end up together as the months, mabye years, you get tired; you end up just acting like you are friends; you later on find out he or she cheated on you! You may cry, feel sad and disappointed because you trusted that person. But maybe later you start thinking maybe it was your fault because you dind't show him or her that much love. While at the same time he or she comes running by begging for forgiveness ...... You are confused because this time he or she comes very sad and giving you more love than ever; showing more love than ever; you are very confussed and start wondering: do I give him or her the chance? or what do i do? You ask for time and he or she stays away and dosen't show more love. You start to wonder again was all this for show, did she or he actually wanted me. At the end you ask yourself; is it worth it, WHAT IS IT?
