All because I can't say no

You know that thing we do all the time?
"I love you, you love me
never together will we be"
Remember?

I'll tell you now
this has to be the last time
Because I can't do it again
every time we end it
my heart burn in my own chest
wanting to stop beating,
begging for the end of this pain...

I sit in my room at night, crying
Wishing I hadn't changed
Wishing things were like they used to be
Back when I could've walked away from you,
when we decided it, without looking back
and without caring
back before I fell for you

I can't do this again
I don't want to feel my heart
trying to tear itself from my chest
I don't want to stay sleepless
for days and days on end
unable to forget
I don't want to be unable to eat
getting sick every time I do
I don't want to feel so lost and alone again
like every time I smile or laugh
I'm lying to the world

I don't want to be alone again
I don't want to be without you again
but I guess it's too late to stop it isn't it?
All because I can't seem to say no to you...
