Hi K.,
This sounds really frustrating. I know it must be so stressful to not have control over the things your son is being exposed to. Does your husband seem to love your son? Is he trying to get back at you with these things, or is he just truly irresponsible? If he cares for your son maybe he would be willing to meet with a mediator of some sort, a psychologist would be ideal. Maybe he would be willing if you didn't choose the person, but gave him a list of some people and let him make the first contact and then go in together. It sounds like conversations between you and your husband won't work very well, but maybe it would help to have an impartial person mediating the discussion and helping your husband to keep your son's best interests in mind.
Good luck,
K.
