In this fan favorite — reportedly inspired by the end of her relationship with singer Joe Jonas — Taylor sings about seeing someone slip away, without really knowing what caused it. She explained in 2010:

""Forever & Always" is about when I was in a relationship with someone and I was just watching him slowly slip away. I didn't know why, because I wasn't doing anything different. I didn't do anything wrong. He was just fading. It's about the confusion and frustration of wondering why? What changed? When did it change? What did I do wrong? In this case, the guy I wrote it about ended up breaking up with me for another girl. Guess I know why he was fading..."

Lyrics-

Once upon a time
I believe it was a Tuesday when I caught your eyes
And we caught onto something
I hold onto the night
You looked me in the eye and told me you loved me
Were you just kidding?
'Cause it seems to me
This thing is breaking down, we almost never speak
I don't feel welcome anymore
Baby, what happened? Please tell me
'Cause one second it was perfect
Now you're halfway out the door

And I stare at the phone, he still hasn't called
And then you feel so low you can't feel nothing at all
And you flashback to when he said, "forever and always"
Oh, and it rains in your bedroom
Everything is wrong
It rains when you're here and it rains when you're gone
'Cause I was there when you said, "forever and always"

Was I out of line?
Did I say something way too honest, made you run and hide
Like a scared little boy?
I looked into your eyes
Thought I knew you for a minute, now I'm not so sure
So here's to everything coming down to nothing
Here's to silence that cuts me to the core
Where is this going?
Thought I knew for a minute, but I don't anymore

And I stare at the phone, he still hasn't called
And then you feel so low you can't feel nothing at all
And you flashback to when he said, "forever and always"
Oh, and it rains in your bedroom
Everything is wrong
It rains when you're here and it rains when you're gone
'Cause I was there when you said, "forever and always"
You didn't mean it baby, I don't think so

Oh, back up, baby, back up
Did you forget everything?
Back up, baby, back up
Did you forget everything?

'Cause it rains in your bedroom
Everything is wrong
It rains when you're here and it rains when you're gone
'Cause I was there when you said, "forever and always"
Oh, I stare at the phone, he still hasn't called
And then you feel so low you can't feel nothing at all
And you flashback to when we said, "forever and always"
And it rains in your bedroom
Everything is wrong
It rains when you're here and it rains when you're gone
'Cause I was there when you said, "forever and always"
You didn't mean it baby
You said, "forever and always," yeah
