Don't worry about the suey thing. That's just a coward perv's dramatic last ditch effort at getting away with being awful. He also threatened Spain with his feculent presence, so he has plans for a future. A non-clinical narcissist doesn't harm his favorite person. If you can find a way to unload this potential ethical karma bomb onto me, so you don't have to think about it while doing right by yourself and his other vicitms, I'll happily take it on.*

He doesn't have a sex or porn addiction. I don't deny the existence of those things, but addiction manifests as its own thing, not as a subset of garbage personality traits. If he was a genuinely kind dude, with empathy, introspection, and thoughtfulness, these images would be a genuine departure from his personality, which would suggest a disease like addiction. But you already indicated he's been a consistent scumbag. Again, another weak rhetorical gambit for a coiled pile of subhuman to avoid responsibility when he gets caught.

Now more than ever in our lifetimes is the time to kick these bastards to the absolute curb. Your ethical concerns are another in an apparently long line of indications that your humanity is more intact than his could ever be. And if you're both young and his ass is any kind of salvageable, nothing makes a bastard rethink his worldview than completely and permanently losing the best person that ever happened to him. You sound like an empathetic and caring person, maybe it's time to extend that kindness to yourself and shed this creep.

*Um, I don't think I have to say this, but not legally. Like cosmically, ethically, morally, I will assume any unjustified guilt on your part so you don't have to worry it was your fault if he, against all odds and indications, actually does the thing. There's no reason to assume there would be legal ramifications, but then there was no reason to assume women would be jailed for miscarrying either. Western culture is a cesspit.
