Fiancé has a porn addiction? Did I make the right decision?

So my fiancé and I have been together 3 1/2 years. He's a great man, every aspect of our relationship is golden. Except one thing. The sex was always great, except this last year together I noticed he started instigating less and it was mostly me who would push for sex. It got really annoying because I have PCOS and high testosterone = higher sex drive. I was getting frustrated. Sexually frustrated. My needs were being suppressed. I started to feel unwanted. I'd wake up in the middle of the night and he'd be in the bathroom. The next morning I'd find porn all in is history. Why? It would make me so mad. Especially since I wanted to have sex with him more than anything. Why couldn't he take it out on me or ask me to go down on him? And it was always busty MILF porn. I'm not anything like that. It hurts me. I had an eating disorder for 5 years and just as soon as I'm completely recovered and feel confident, I have a partner who makes me feel bad about my body image. I discussed it with him and it's simply because he loves porn. But it hurts me. A lot. Especially when it replaces our sex life or he can't give me full effort because he already used it all up earlier in the day without me. I feel like it's selfish. I asked him multiple times to start taking his urge out on me, but nothing really changed. He started lying and deleting history and it was hurting me. I broke up with him and we still live together. I love him more than anything but I can't forgive him for the life of me. He's really a great man and at the end of all this, he doesn't want anyone else. Should I forgive him and work with him or should I just move on?
