i hate him so much

why when i want to forget about him..suddenly he appear back in my life..fo a long time he didn't contact me,,suddenly contact me back..it really annoyed me..i hate when guys that lied to me n once upon a time,,after i clash with him,it fne to be friend but he said that he still love me..n i maybe still had a feeling to him...so i keep his word but how foolish i am...i realise that he's word that time juz a sweet word..when i had a problem,,it really difficult for him to help me..n he never contact me...i had delete his phone no n facebook..i really don't want him to be in my life..it really hurting me a lot..when he contact me back,i think the reason he contact me coz he want me to help him to find a book maybe..n what the reason is it...i don't want him to be in my life again..i wish i could forget everything n after that,,if he's class same with me,,then i don't care about him anymore coz i had already forget about the past..
