Get the nashmug. the boy who broke my heart. the one who ripped my heart out and threw it on the floor. because of him i am broken. i can’t love myself or anyone else because of him. because in my weakest and darkest hour you threw the final punch that knocked me out of the ring forever. if you read this Nash, thank you. thank you for being such a big waste of time.
