This Is Really Goodbye ( Should I?? )

I've just opened my MP3's playlist, and I found this Korean song,,,This is the lyric of drama Korean, sung by M2M. I've search the English meaning in Google and I found it as well. Read this lyric, reminded me of someone that I should've let go from now on..wanna know see this lyric..

Where did you go, the you who just passed me by and left?
Are you doing fine, at a place without me by your side?
Hoping you’ll come back, the times I’ve waited for you
I’ll let it go now, I’ll forget you now

The beautiful times we had, they’re all memories now
The tears I shed when I missed you like crazy
Hoping you’ll come back, time stood stagnant
I’ll let you go and leave now, goodbye

Couldn’t you find it, the road that leads back to me?
Should I wait a little while more, should I wait here a little longer?
Hoping you’ll come back, I waited all this while
I’ll let it go now, I’ll end it for real

My love for you that I held on so tightly, is slowly dissipating
The me that went crazy missing you, is gradually changing
Hoping you’ll come back, time has stood stagnant
I should erase it all now, for real

My love, it ends right here, this never-ending yearning
Stuck in my throat, I couldn’t say it
Those heartbreaking words of parting

All my beautiful memories of you, it’s leaving me right now

Like falling tears, my love is slowly dissipating
The me that went crazy missing you, is gradually changing
Hoping you’ll come back, time stood stagnant
I should erase it now, for real

Should erase it now,
I should forget you now,

Goodbye.

So, can you read all of the meaning of the song. I didn't concern about the grammar, but the meaning..hahaha..

I think, I should erase "him" for real..

But still, say goodbye to all of the meories we've been through..is not as easy as you think
