A unique, but I feel appropriate metaphor in some cases. I feel as if he is cheating on me and I’m aware of it and unable to stop it. Heroin is the mistress and I have to watch as my boyfriend walks out the door and goes to her every day. That bitch gets all his time, all his money and all his thoughts and she honestly doesn’t even make him happy. This is what addiction feels like to me being on this side of things.
