So no, i can't explain myself

So how can I explain, how can I explain that I stabbed you in the back? Oh, I stabbed you in the back, oh yeah
How can I express, how can I express that I want to take it back? But I just can't take it back
And all this time you've been waiting for me, I can't believe I let it come this far
Away from what we thought you meant to me, I can't believe it, and I hate who I've become

So no, I can't explain what happened to me and why I thought that we could make it through this
I can't believe that this is me, and why I've been acting so contradictory

So how can I explain, how can I explain I stabbed you in the back? I stabbed you in the back, alright
How can I expect, how can I expect you to call me back? But you keep calling me back
So now I'm begging you to understand that even though I threw it all away,
We were meant for something so much more than absolutely nothing, I just can't quite figure out who I am

So no, I can't explain what happened to me and why I thought that we could make it through this
I can't believe that this is me, and why I've been acting so hypocritically

And I'm sorry, but sorry doesn't cut it like the knife in your back
And I'm sorry, so sorry, but I'm done this is my last regret oh yeah, oh yeah

No, I can't explain what happened to me and why I thought that we could make it through this
I can't believe that this is me, and how I have become my own worst enemy
I can't explain what's been going on in my head
I can't believe, so I'm begging you please forgive me now
