Hey Matthew! In this poem, you are exploring an age-old concept - and, while this is perfectly acceptable, I'd recommend doing it in a more creative way than the literal statements that make up the majority of your poem. For example, saying 'it's always my fault' was not terribly enticing as a first line - maybe if you'd started off by narrating an incident and sort of subtly suggested that your fault was implied.
However, I definitely enjoyed this piece as lyrics and I think you should maybe throw it in the lyrics section as well, to see what people think of it there. For some reason, I had the Michael Buble song of 'Just Haven't Met You Yet' stuck in my head as I was reading this and the tune seemed to fit really well - kind of upbeat and happy-go-lucky,and thus it lightened up an otherwise deep and dreary theme.
