The most empathetic thing I can say about your H is that he seems like he's in an emotional vortex and making highly impulsive decisions. He does not sound like someone who has undergone deep introspection and made the kind of lasting change you are looking for. He sounds like someone operating under a lot of fear and emotion and making dramatic gestures like showing you that box of cr*p.
True lasting change is evident over time. It is not dependent on the daily fluctuations of one's emotions.
Hang in there, you have a lot of people here rooting for you. Things will get better.
