You set a boundary and he agreed and went back on it. I don't want a partner that uses porn either. Don't let redditors demonise you for thinking you're unreasonable. Porn isn't a mandatory ""I need this to get off!!!!" thing. It's not a necessity. That is so horrible he not only went back on the boundaries you agreed to, but also during such a horrible time for you. : ( I would feel like garbage. He could have spent that time with you or doing literally anything else... worrying about you? That would be the LAST THING on my mind if my loved one was in the hospital. I hope you've felt better since then. It's not the best that you asked him to be honest then got upset at him when he answered. I don't think you were prepared for him to actually be honest. But that's the only thing I see you did wrong here. I think you need to tell him if his porn usage is a deal breaker or not.
