What does this poem mean?

In my view, whoever wrote this has some serious issues. It sounds like someone venting on paper because they are in an abusive relationship. Why else would they not want to say those things to someone they are close to? It is a bit of a control issue like, "I can't control you, but I can control what I say to you." This is one way of having power by withholding tender emotions. Pive aggressive behavior.
