Forget the past.... Is it possible to let go ?

Somebody once told mi you have to let go out ur love for someone that is the past before u can move on to the next relationship... But is that really possible ? Even though i never gotten the ger i love but the love for her never diminished.... I have not met her for a yr or more... today she came to my hse to return mi a set of vcd i lent her... The moment i set eyes on her... all the feelings n emotions i haf for her came back very strongly. Yes she is getting engaged soon. But fuck that... There is still 4 month... i am such a bastard @ time but i am also a coward. I dun dare to make any move. Neither do i wan to also... Becos i know he is a very nice guy with ambition and is very caring n take good care of her. She is very very happy with him together... But then i juz cant get the feeling off... I still remember the past. Not a single bit have been lost. I remember the places i visited with her. I remember the one n only show i watch with her. Water boy... I remember wat we ate b4. I remember the route we took to sent her home. I remember the day i weep when she rejected me... Every thing.... How am i to forget it n proceed... Though i carry a liking for another ger whom i noe is impossible but wat to do... She is the ger who told mi i have to forget the past to move on...
Why... alot of times i have seen guys who gamble n lost so much.... seen guys who drink everyday... known guys who flirt ard... yet they always have a very caring n pretty gf... Yet i am here all alone opening telling the world wat a failure i am.... I juz dun get it wat do i lack...
Some comment was thet the one is not here yet... Well everyone know thats juz a excuse to make mi feel better. Thanks to all the people who try to make mi happy with those petty excuses and thx to those who have already give up on me. I mean it. I am such a jerk n make people ard miserable. Y do i grumble so much....??? Such a pussy i am.
I guess i am real stubborn @ times with my thinking but it seems that i am losing alot of frens. People who juz lost contact or juz dun wanna reply my msg anymore. Guess i am a failure in both love and friends and worse of all i am a failure in life...
ORD on the 25th yet i am still so slack not sending out resume... As if job will drop from the sky... My ambition have left me... I have no morale left.... No fighting spirits anymore... Sorry Montfort. Age Quod Agis.... i dun think i can fulfill tat anymore....
