Could Have Been Mine

So you say your new girlfriend's a little too friendly
You caught her telling one more lie, one too many
You say she won't love you right
She stays out so late at night
Lately you've been thinking about the time
You could have been mine, you could have been mine
It wasn't very long ago you had my attention
And what she did that turned your head, well, I won't mention
I won't say I told you so
But there's one thing you should know
I was seeing hearts and valentines
You could have been mine, you could have been mine
That's the chances we take
With the choices we make
There's gonna be mistakes from time to time
And you could have been mine
Now you've got your bed all made so lay alone in it
Don't even think what we could've been for even one minute
I'd have been your Juliet
And never gave you one regret
But don't you let that cross your troubled mind
When you could have been mine, you could have been mine
That's the chances we take
With the choices we make
There's gonna be mistakes from time to time
Oh, you could have been mine, could have been mine
