Firstly, because it's HIS, not mine. Secondly, it is perfectly under control here, and is doing no harm. It would also be a gross breach of his trust in me. He always thought I would throw everything away, but apart from one horrible cheating episode, when I threw things out of the window, I am proud to say I have not let him down. I know how upset he was when Janice disposed of a lot of his things, and I'm not going down that path. I have seen the trauma screwing around with his things causes, and I don't wish to add to it.
He helps me a lot, whenever he can. I can't change the past and make him loyal as a partner, (nobody ever will) I can maintain my own standards of treating other people decently though. And if it ain't broke, don't fix it.
Over the years, I have learned a lot about hoarding. I understand, and it doesn't bother me like it used to. I have plenty of space for my things and my life now. I don't intend to make him feel violated.
We are close and intimate, we still engage in naughtiness. I don't need or heed silly advice.
