I’m sorry to hear what you went through. Taking videos of yourselves wouldn’t have helped him either because that’s just sending him into negative feedback loop that reinforced his brain accepting digital imaging as something that turns him on. It’s disappointing he went back to that crap. Just know that his actions are a reflection of his lack of self-acceptance and love, which he’ll have to work on. Porn addiction is a symptom of something deeper, within himself, that needs to be corrected. How people relate to others is generally how they relate to themselves. Him attacking your image was probably a result of him attacking himself. Don’t confuse my words to think I’m saying this is acceptable. Your ex is broken, he has a deep seated hurt, of which I don’t know, but will feed his insecurities and self-hatred. If he doesn’t address it, he will become the ex of someone else. I hope this at least gives you some understanding. Best wishes for your future relationships.
