I Can Give You No Love, Only Dead-lift of Pain

I was ready to give it all,
but you caught me in mid-fall,
bringing me back to complacency,
or lower, I mean.
I mistook that look as a cry for help.
"Someone save me from myself!"
Well...
you broke my heart and I killed yours.
You torment me, pouring salt on my sores,
yet I am still the double-edged razor.
Would you crawl through broken glass to me?
