can one measure heartbreak?

I didn't even know how much I liked you
until you said you don't like me back
no, not really
not "like that"

I feel quite silly to be honest
I don't know what I expected
my life has always been a series of platonic,
unrequited love
that I recollected

it's okay, I'll get over this mistake
— maybe have one too many cakes —
'cos in the end
I'm always just waiting for my heart to break.
