I'm still trying to figure out how to tell you I was wrong I can't fill the emptiness inside since you've been gone 

So is it you or is it me? 

I know I said things that I didn't mean 

But you should've known me by now 

You should've known me 

If you believed 

When I said I'd be better off without you 

Then you never really knew me at all If you believed 

When I said 

That I wouldn't be thinking about you 

You thought you knew the truth but you're wrong 

You're all that I need Just tell me that you still believe 

I can't undo the things that led us to this place 

But I know there's something more to us than our mistakes 

So is it you or is it me? 

I know I'm so blind when we don't agree 

But you should've known me by now 

You should've known me 

If you believed 

When I said I'd be better off without you 

Then you never really knew me at all If you believed When I said 

That I wouldn't be thinking about you 

You thought you knew the truth but you're wrong 

You're all that I need Just tell me that you still believe Is it you or is it me? 

I know I said things that I didn't mean 

You should've known me by now 

You should've known me 
If you believed 

When I said I'd be better off without you 

Then you never really knew me at all If you believed 

When I said 

That I wouldn't be thinking about you 

You thought you knew the truth but you're wrong 

Cuz you're all that I want 

Don't you even know me at all 

You're all that I need 

Just tell me that you still believe
