There is more to it, and it's hard to pinpoint cause and effect. He did have issues that existed before the pornography habit. But they worsened significantly since the month he started looking at pornography regularly. I do believe that his pornography habit has lowered his mental and emotional intelligence by a noticeable factor. I also look back at when I was his same age, and see my own struggles as very similar to his. So I could be mistaken with some of the internal presumptions I've made about him, but the external ones match up almost exactly.
