Hi MA.
I love the analogies running through this and their relationship to the title. I recognised parts of this, the pettiness that consumes you but is hard to let go of, as it sometimes feels like the only control you have within the relationship. There's also an element of the co-dependency, knowing the drama of the behaviour is part of what keeps you together. I'm probably way off but it's how your piece has made me feel and I think you've written it beautifully :-) x

There's a lot I want to say, and a lot I recognize in this poem, but will just say this: you really should consider publishing your work.
