The "new girl" enter your life

Today i go to your facebook and see your wall...maybe that is my habit already now..as i wanna know what you are doing...what you are thinking...today i saw you added a girl..dont know why...i felt that girl so pretty...the cup of tea of every men..suddenly my heart felt down...i felt unhappy that moment..maybe the feeling of jealous???or maybe feeling of worry???still remembering that the time we together, you told me you wont add any girl that you dont know...maybe you know that girl...but dont know why...i think you are falling in love on another girl now...so that is the reason why you dont want to be too closer with me...i always ask my self dont think like that...dont think too much...but i really dont understand why you want to ignore me, leave me...you promised you wont leave me no matter how difficulties the road ahead..you promised you wont ignore me no matter how the difficulties things happened on us...you said you would hold my hand my hand tightly towards the difficulties together with me...but why you would able to forget all things like nothing happen even...??i really want to know...
