"Thank Me Later" lyrics

Is it supposed to be like
A never-ending train ride
Or waiting for a grey sky
To turn to sun

Our kiss lost all the sweetness
We talk like we're defeated
We're just scared of being quitters
After this long

Someone should say the words we're choking on

I need to let you go, let you go
It's better for us both
You don't see it but I'm doing us a favor

I need to let you go, let you go
'Cause when you know, you know
And it's hurting right now, but you'll thank me later
I need to let you go

Let's not decorate the sadness
Let's just rip of the band-aid
And hug and say it's ok
We stop right here

The sooner that we're not together
You'll find someone better
But if we're gonna get there, if we're gonna get there

I need to let you go, let you go
It's better for us both
You don't see it but I'm doing us a favor

I need to let you go, let you go
'Cause when you know, you know
And it's hurting right now, but you'll thank me later
I need to let you go

I know nothing's ever promised
But I hate walking away
'Cause this isn't how I saw-it
Tears running down my face

I know nothing's ever promised
But I hate walking away
'Cause this isn't how I saw it

I need to let you go, let you go
It's better for us both
You don't see it but I'm doing us a favor

I need to let you go, let you go
'Cause when you know, you know
And it's hurting right now, but you'll thank me later
I need to let you go (Let you go)

(I know nothing's ever promised)
(Let you go, when you know, you know, let you go)
'Cause this isn't how I saw it
I need to let you go
