Hesitating...

Hello peeps! 

                    I am seriously thinking of giving up this relationship with that boy.... But i am afraid if i give up, it will be a big blow to him! If i say i want to break up with him, he cannot concentrate his studies or maybe the opposite. Will he hate me? Y wud i give up this wonderful relationship? I guess that everyone HATES rumours! Neither me, like rumours. In my class, everyone says that my bestfriend like the boy that i was in relationship now. At start, i could not believe this! Until i starting to Suspect her. She was treating him better than anyone else.So many of you thinks that i am thinking of giving up this relationship because of her. Because of love rivals. But i believe that If we luv/like each another truly, nothing can stop us. But i hate to fight things with someone. Really, i am tired of EVERYTHING!! Now, i just wished to concentrate on my studies and score well n go good school. Can my goal be completed? Love rivals, and all sorts of nonsense are starting to get into my ways. Is giving up the best choice to solve this problem? This problem is bothering me for awhile. Is concentrating on my school work or studies so though? Haha, thinking back now, i was so foolish of accepting this relationship. If i give up, i can concentrate on my studies... Someone help me pls!!??
