Why don't you fly away [bird]?

Fly, fly, fly away! Go! I have plucked every feather off my body, but you are hesitant to even pluck a single one from yours! I will not let this slide. Fly, fly, fly away! Go! You have no use being here; I have thrown my last crumbs! I have nothing to give! Even if I shall have a single crumb, I wouldn't dare toss it out to you! I will not let this slide. Fly, fly, fly away! Go! Find another that will toss out every crumb they own to you! Find another that will pluck their feathers for you! Oh- there is no other in sight? Fly, fly, fly away! Go! Meaning of poem for those who are confused: This is about you guessed it... a toxic relationship. One partner is giving everything to their partner and is receiving nothing (not even the bare minimum) in return.
