Yes, long after we've understood that a relationship is dead, do we actually make that move to end it. We hang on stubbornly, or defiantly hoping that things will change. Irrational thoughts, but such is man.

The writing is good. You mix simple language with craftsman-like structure. If more writers understood that it isn't the words, but how they are constructed, then poetry would be a more pleasing reality. Yours is a good example. You understand that the beauty is in how you arranged the wording, the structure, not in trying to find big words in a thesaurus and constructing them in ornate and wordy forgeries.

The subject is clear, we've all been there, facing the end of a relationship, angry that it is over. Not all ending are this acrimonious, but they all have that hurt, and we often lash out in language we probably later regret.

The theme is to be commended. Often writers in this genre tend to focus on the hurt and end up somewhere in a field, far from their original theme. Their anger keeps them from focusing, from being logical.

The last line says a lot. For some anger, sadness, etc is how they (we) cope. It' a good poem.
