history text book

he came to my house to pass to me his history text book. he promised to give me the book. so... i thought i already forgot part of it about him but when i saw him my heart straight away break into pieces again. i really feel so sad now. i know i should not be like that. i'm trying my best. i guess i still need more time. why is he so hard to forget? i should not be sad anymore. i wish i could be stronger. i don't want to cry but i can't control it. is it so painful when the one you love go away like that? or i'm the only one that feel so? haih.
