I'm tired of this relationship

Seriously, you're making me tired of this relationship. I gave all the first priority to you and in return, what did i get? What i can say is i get a stab from you into my heart. Do i really deserve this from you? I'm tired of looking and hearing on how you replied me and there my tears burst. If i had a chance to choose, i will make our relationship to stop. This relationship is blocking my way to do my things especially in my studies !
