Just let me keep you to myself

I can't explain it
The desire to call you mine
Without knowing what I'm feeling
I can't tell you what's going on

I don't want to share you
I'm scared
I don't want to be put second best again
I felt it happened, you only talked about him

Arguments ask me why you hold on
Why do I hold on?
You'll always have control over a part of me
That's something I cannot change

You isolated yourself in my heart
I can't give half a broken heart out
Blood drips as I hold it in my hand
Inspections never lead to my hands emptying

What keeps us from letting go?
Is it the promises we've made?
Could it be the feeling of acceptance that we shared?
Or are we just fools, chasing our shadows in the dark

I've cornered myself, there's no way around it
