What are we?

I want to share my heart with you
But you have relegated me
Mid-way between friend and lover
I hang here, unbalanced
Not knowing
Uncertain
Afraid to ask
What is the job description for this role?
Can I say I love you?
Is that allowed?
I am enveloped
My heart pressing outward
Threatening a cataclysmic explosion
I will myself to hold it in
Hands fisting
Palms bleeding
Eyes leaking
Evidence of the pain
Of the fractures
I silently beg for an end
Tell me now
What are we?
