How can I?

How can I tell someone I care when they don't?
How can I tell someone I think about them when they don't think about me?
How can I let myself feel after all they've done?
How can I let myself fall when they won't?
I can't but I want to.
I want to tell them I care too much and I think about them too often and even after what they did I still want them by my side.
But I will hide behind my poem and behind my smiles as if they are the last thing on my mind.
