I think I have to leave - would you?

My boyfriend struggles with porn addiction.

It got to the point where he couldn’t hold an erection, he would get soft because I wasn’t porn, we would go weeks to months without sex, and he started ignoring me. He would watch it every day, every hour, and sometimes he said he just watched it to watch. He started getting off to normal everyday things, Amazon, Spotify, health websites, random things. All of this came with lying, doing things behind my back, and constant betrayal. I left but came back after a few months because he promised all of that was in the last.

Now, recently I’ve caught him lying again about two small insignificant things. So I wonder if he’s lying about small things what big thing is he lying about?

After this I just shut down, I’ve gotten mean and angry because I’m going through this again. I tried to be understanding but I can’t anymore. He promised he would talk to me about any urges or slip-ups. Not because he has to report to me but because he wants me to keep him accountable since he refuses therapy. Well lately, if we do have sex, he doesn’t cum a lot. I feel like I’m getting crazy and when I have mentioned it and just tell him that I’ll be there for him is he’s slipped up but that id like to know. And he denies and denies but we won’t have sex for days and then he’ll still barely cum. Porn was something I didn’t prefer before but now after dealing with this it’s a dealbreaker. I feel like I can tell when he’s done stuff but it just causes friction to ask so I don’t. But I want to be in a healthy, happy relationship. I don’t want this and I love him so much but even he deserves better.
