not threaten D, but make it clear that he won't tolerate this cr*p anymore
Well, from what I know of Mrs HD, it will be VERY difficult to pull that off without the threat of D, or at least S. I doubt my H would have been able to take a firm stand without taking a drastic measure. Why? Because that was just not his personality. I doubt it is HD'd either. Nice Guys have a very hard time with this whole boundary issue. And frankly the women they are M to (such as myself and Mrs HD) can be quite bitchy. Doubt we'd believe a word without some major action. S did it for us and it CAN work. I'm not advodacting that just saying it is not always the worst thing to do, in fact it can sometimes turn things around.
