You are very saintlike to still have the desire to stay but I would have turned my back and left... this is coming from a PMO addict. I don’t like that he leaves the house when you’re crying even though he’s the reason for it. To me, that shows he has checked out of the marriage somehow and he’s trying to live his life as conveniently as possible for him. He wants his porn life but he also wants you to stop “nagging” him about it. The more you “nag”, the more he feels disgust and rage toward you for getting in the way of his addiction. I would just leave him to it. All the signs point toward him lying to you and taking you for a ride.
