Should've Said No (feat.Taylor Swift)

It's strange to think
The songs we used to sing
The smiles, the flowers
Everything is gone
Well, yesterday I found out about you
Even now just looking at you
Feels wrong

You say that you'd take it all back
Given one chance
It was a moment of weakness
And you said yes

You should've said no
You should've gone home
You should've thought twice
Before you let it all go
You should've know that word
'bout what you did with her
Would get back to me
And I should've been there
In the back of your mind
I shouldn't be asking myself why
You shouldn't be begging
For forgiveness at my feet
You should've said no
Baby, and you might still have me

You can see that I've been crying
And baby you know all the right
Things to say
But do you honestly expect me to believe
We could ever be the same
You say that the past is the past
You need one chance
It was a moment of weakness
And you said yes

You should've said no
You should've gone home
You should've thought twice
Before you let it all go
You should've know that word
'bout what you did with her
Would get back to me
And I should've been there
In the back of your mind
I shouldn't be asking myself why
You shouldn't be begging
For forgiveness at my feet
You should've said no
Baby, and you might still have me

I can't resist
Before you go tell me this
Was it worth it
Was she worth this

No, no, no
No, no, no

You should've said no
You should've gone home
You should've thought twice
Before you let it all go
You should've know that word
'bout what you did with her
Would get back to me
And I should've been there
In the back of your mind
I shouldn't be asking myself why
You shouldn't be begging
For forgiveness at my feet
You should've said no
Baby, and you might still have me
