Fall Back

I need to do this on my own
its time for me to walk away
i cant live my life like this
wondering how long you'll stay

it kills me every time you leave
but i no you'll be back eventually
when no one else wants you
you'll come running back to me

Ive finally realized who you are
and how much you don't care
but the next time you come running
I'm not gonna be there

I'm sick of the way you use me
and your sweet talk to make me crack
but as much as i love you
I'm sick of being your fall back
