Why am I still hurting now?

I don't really understand what's happening to me...
I don't know why I'm feeling very very very hurt...
I just saw that he was 'engaged' to his new girl...
I could feel the unshed tears burning in the back of my eyes,waiting for the right time to come out but I kept myself in check and held back the tears..
No,I wouldn't let it come out...
I wonder why I'd cry for just that little thing?Perhaps I still love him?
I don't want to believe that I do but if I really do,then I just have to come to terms with it...
I wonder when this pain will end because I just don't know how long I can bear with it~
Rest in peace,my little heart~
I hope I wouldn't break you anymore~
I should just let him live his life..
If I do love him,then I should just back off completely and let him be happy~

Since that's what love is all about- sacrificing for others~
