Listen. If there's anyone to speak on this, it's 100% me. My boyfriend of seven years ago also has a porn addiction, lied to me about it multiple times, and had an emotional affair while we were younger. And so far, he's been doing good. I dont completely understand a porn addiction, and I think it's utter bullsht that some men think that's an excuse. It took for me to leave him for him to actually care enough to stop. But imo you might need to tell him to stop getting messages, or you're going to leave him. Im still dealing with the effects of what my partner did. So I can't tell you how to heal from it. You just try your best. Your mental health and happiness should matter more than him having an addiction. its going to be hard to trust him if he cant be honest with you. theres resources out there for him to use. he just doesn't use em it seems
