>You are feeling lose as you are too used of having her
around.
>Time spent together,places appear vividly in your mind.
>Hearing she had a new guy is the worst shit in your mind.
>Setbacks of what you always charish most has been taken by
others.

Yes, she will always be a part of you,forever within your heart
& soul.
What i propose(might be cheeky/own experiance), since the most
devestating outcome has already been told.(Of cos in a guy
perspective/i'm pratical)
>Live life to the fullest.
>Faster get another victim to ease your pain.(It works for me
& some friends.unless you really see other pretty girl on bed
dun turn you on)
>Get on from here.
>Tell yourself she does not deserve the love from you.
>There are many females that are readily willing to settle down
if you are the one.
Good Luck Bro,things are not as bad as it seems..
You are just too used of having her by your side. 
Soon, things will change as the feeling/passion "dan hua" & of
cos with a new person standing beside you, giving you the support
in everything you do.
>Sometime ppl say early break is better then late divorce is
true...
