That happy ending

I cried my last tear
I finally waved goodbye
Now lets see how long I last
Before I try to pass, on
You wont be here today
You wont be here tomorrow
You said youd give me the world
But today is tomorrow
And yesterday is in the past
Im smart enough to realize
Now, youre never coming back
No matter how much I cried
Or how much you cursed
No matter what I said
Or what you did
We just werent meant to be
But theres someone out there
Thats waiting to find us
And when we're apart
We'll find that happy ending
