Please help.... I just need some opinions

I’m 25 weeks pregnant and my fiancé has had a problem in the past woth pornography and we’ve talked how it hurts me and so on. We worked through it and now I found out that he is watching numerous videos on YouTube of woman working out, close up on them bending over, diving videos of the camera slow motion zooming on their asses. It hurts because he is a peace officer and has been sneaking off at work for hours to watch these videos....I feel hurt inside and when I confronted him he admitted he has an addiction to watching those woman and admitted to being in lust with those woman. I guess hearing those words really broke my heart because not only am I pregnant but I’m not feeling as pretty growing n gaining weight. I’m lost at what to do or if this is even fixable? Because I feel like I’ll never be good enough for him and want him to lust over me.... am I wrong to hurt?
