Therapy. He needs to be fully dedicated to it. My husband tried to quit cold turkey and failed repeatedly. He had to disable social media, put parental restrictions on YouTube, add accountability software to block specific websites. It wasn't because he wanted to, it was a habit. You know how you get bored and just absent mjndedly pick up your phone and bring up Instagram or reddit or a mobile game or something? That was soft core porn for him. He'd be six pages deep in a reddit thot's profile and realize, oh shit how did I get here.

Once he started therapy and really took steps to change his absent minded actions, that is when change happened.
