You don't have to put up with his behaviors. You could easily meet another guy who doesn't engage in those porno activities. I wouldn't trust him and you should leave as promised because there's no telling what you're getting into by being with a porn addict. I've been in a relationship with someone just like him and he was horrible I can only imagine what you are going through. He was always cheating on me and he chased after very young women even in his forties. He stayed out all weekend and longer...it just went on and on.
