I'm The One

The only thing I can think of is the word hurt
Which leads me to replacement
And then I think mend
Because I want to, but I know I can't if I place myself
In the exact situation that breaks me down
Slowly but surely
Because I used to be the one hung on your side
I used to be the one cuddling up to you
And I used to be the one you walked off with and left the others behind
But now I'm the one to fall back and watch you in step with another
And I'm the one to stop walking and you never realize I'm even gone
And I'm the one to go home and give myself a reason to wear sweaters in the heat
And I'm the one who has to deal with it
So maybe I deserved to be replaced
By someone who doesn't need sleeves to hide her disease
So maybe I deserved to be hurt because I dished it out enough
Maybe I deserve to fall behind because I ran off and ditched another
How could I expect life to stay the same while I was gone?
How could I expect that you wouldn't try and move on?
How could I expect that change doesn't exist?
This is how: my heart runs on ignorance.
