The foundation of a good relationship is communication and trust and you are now aware of his addiction, because porn like a drug, suck you into it's web, which is then hard to resist and become as problem. Unfortunately, you are out of the apartment most of the day and there is where he takes advantage and goes for it. I would no longer try to talk "nice" to him and I speak only for myself that I would total access to the computer (he can also delete the history easily) and if the behavior continues, you will need to re-evaluate if this is how you want to continue in this relationship. I don't see him doing anything else, so I would tell him like it is. "I'm concern at the amount of time that you spend watching porn and I now can say, that you have an addiction, what are you going to do about this." Tell him, "I'm now bothered, concerned and hurt and I want YOU to take care of it or this relationship is over:....no more nice, straightforward and to the point. Good luck...Judy
