Lyrics

I   now it's time
For me to   up
I   it's time
Got a picture of you   me
Got your   mark
Still on your   cup
Got a fist of   emotion
Got a head of   dreams
Gotta leave it
Gotta leave it all   now

Whatever I said,
Whatever I did I didn't   it
I just want you back for good
Whenever I'm  
Just tell me the song and I'll sing it
You'll be right and understood
I want you back for good

Unaware but underlined
I figured out this  
It wasn't good
But in the   of my mind
I celebrated  
But that was not to be
In the   of separation
You   at being free
Can't you find
A little   inside for me

Whatever I said,
Whatever I did I didn't mean it
I just want you back for good
Whenever I'm wrong
Just tell me the song and I'll sing it
You'll be right and understood
I want you back for good

And we'll be  
This time is forever
We'll be fighting and forever we will be
So   in our love
We will never be   again

Whatever I said,
Whatever I did I didn't mean it
I just want you back for good
Whenever I'm wrong
Just tell me the song and I'll sing it
You'll be right and understood
I want you back for good

I guess now it's time
That you came back for good
Legend

Meaning

This couple broke up (separated), but he could never get over it (forget about her). They’re not together, but he still has her photo beside him and her lipstick mark on her last coffee cup (he didn't want to clean it because he wanted to have a memory of her), because he never wanted to forget her. She, on the other hand, seems to have got over it and has a new life ("you excelled at being free").

Pride kept him away, but after a long time, now he is ready to give up and swallow his pride ("now it's time for me to give up") and deeply regrets everything that happened. All he wants now is to be together again. He’s not very sure if it was his mistake or hers, but all the same he wants to make up for anything wrong he made. He is willing to do anything to have her back, and this time, forever (for good)
