Bf has a porn fetish

So my bf of almost 9 years has a porn fetish. He says Pornhub and Redtube aren’t enough for him. He said he’s more into the homemade stuff because it seems more real to him, but I found something that just disgusted me. He had paid 3 different woman (porn stars) to send him personal videos of them masturbating in 2018, he made an only fans account but didn’t subscribe to anything, and I found an app where you lock pictures so they’re hidden. He had a password which I couldn’t figure out but I found an app where you go to face swap. I clicked on it and looked at the photos he had edited and they were pictures of naked girls (porn stars) with faces of 2 people I knew. It made me so upset and I literally went through his phone to see if he was cheating but didn’t find anything. When I confronted him, he admitted to the face swap pictures but said he’s never done anything else and had no intentions of going any further.

These past 9 years he’s been faithful, he saw past my flaws, he was there for me every day while I was depressed and suicidal, he was there for me when I had issues at home, he helped me financially with college, and so forth. I don’t want to break up with him over his porn fetish but I just feel uncomfortable. He immediately deleted all the apps and I told him if I see another porn fetish thing on his phone that I’m leaving him and never coming back. He said he was ashamed of himself and is going to change, but how do you move on from this? He was masturbating to people we knew and it’s just gross to me... idk what to do....

Update:

The next morning we talked again, and he literally had a breakdown. He said he was so ashamed and disgusted with himself. He said he’s willing to go to counseling by himself or with me or do whatever I think is best for our relationship. He held me and told me how sorry he was but that regardless of what he did, it has nothing to do with me. I asked him if he’s even ready to be in a committed relationship since we’re living together and talking about getting a house and getting married. He reassured me that he loves and cares about me and that he wants to be with me. After we talked he spent some time alone just crying. He showed me that he does want to change for me and I told him that I’ll try to move past this but if I can’t, then I’m moving on. He respected my decision and is trying. Thanks to everyone for the advice and I hope this is something my bf and I can move forward from
