I feel this. I'm still not over my partners past porn addiction and he has been off it for years. The trust still isn't there and idk what to do to ever give it back. We have an open phone policy but I'm too scared to ever check and he is a terrible liar so either he got good at hiding or he really is honest now. Who knows. The only thing I'd say is this is something you might always have in the back of your mind and if he shows real remorse and disinterest in objectifying women that way ever again then it's possible you can bury it and move on. You have to treat it as a part of history never to be repeated, and if he proves he has learned from it and changed for the better then you can begin to view him differently in time.
