If I understand it correctly "porn addiction" is when men prefer pornography to having sex with their wives and will neglect their marital sex life due to a preference for pornography. Obviously that's far different from a husband casually watching porn on occasion. I believe your husband falls into the former category, correct?

I think the danger with your question here is that you're looking for an explanation of why *your husband* is the way he is, and that's probably a very complicated answer that likely has nothing to do with someone else's porn addiction.

If you read the book "Passionate Marriage" it points out that people are subject to assigning simplistic explanations to highly dynamic interconnected systems.

The "why" you are seeking may not be knowable. I think the issue to focus on is what you do with it. If you have addressed all your issues and become a spouse that only a fool would leave, then either your H will commit to the marriage or he won't, and each has it's own set of decisions for you.
