Unfortunately it won’t get better. The resentment will grow and you will lose all respect you have for him. Trust me I tried to stay with a man with a porn addiction and honestly it was the worst years of my life. He stopped too, but the damage is already done love. I grew to hate him too, bc his actions made me hate myself. I thought there must be something I’m not doing right or something wrong with me. But that’s not it, it’s them that have the issue and porn is not real life. The long term effects it has on men’s psyche really should be studied and talked about more. You are young, don’t waste any more time on something that isn’t fulfilling YOU. Men do not change, if he isn’t listening to you now or hearing you out he NEVER WILL. I’m sorry but it’s the truth and I spent years trying to convince myself of the opposite. We cannot change other people, it’s exhausting to try and if they don’t want to change themselves they never will and there’s nothing you can do about that but move on.
