When to Let go?

I've held on 
since years that have gone 
never thought of leaving 
these oh so stong feelings

I loved you with the thought 
that together we'll give it a shot
you left me with nothing 
but lots of sighs and huffing 

I think of you for hours together
I think of you in any kinda weather
I think of you whether i'm happy or sad 
I think of you when I'm cool or mad

I dream of you at nights so cold 
of you and me together getting old 
I wake up with a smile on my lips
come back to reality with certain bad trips

I gave you my heart I gave you my soul
I keep you safe in my eyes, guarded by my kohl
There's still a hope that you'll come back 
you said I'm Rose but hey you're not Jack 

Day after day my love getting deep 
what's the use? every night that I weep 
they say this is the ocean in which i'll never swim
I say I will! I'm madly in love with him

friends have lost all hope 
they say there's no scope 
my heart in the bin I throw 
so tell me when's the time to let go?
