Pornography

A while back my boyfriend confessed to me that he was addicted to pornography through out middle school and most of high school. One time he let me borrow his computer for school work and I had a feeling that he still has this addiction. There was naked women in his search history. I personally don’t want a guy who watches porn and he had told me that he doesn’t watch it anymore. How should I confront him about it? Personally I don’t want a guy who watches porn. He’s also mentioned that he doesn’t want to watch it anymore so yeah idk what to do.
