Learned boyfriend watches porn

So I've been with my Bf for 4 months now, I've known he has a porn addiction since pretty early on. He said he doesn't like it and he feels horrible anytime he watches it. He said he was working on quitting. We haven't really talked about it in a while. But I recently learned that he's been watching it almost everyday again for weeks. I know it's 'normal' for guys to watch it, but we've had an open discussion in which we BOTH expressed not being ok with it. I guess I'm just upset that he doesn't seem to be trying anymore. And maybe I'm being sensitive but it makes me feel self conscious. I wonder who he watches and what they have that I don't. We talked about it and he told me again, he's going to work on it. That's he's sorry.But he'll talk about how he's struggling with it today and then we won't talk for a few hours, and when I ask him how he did today he dodges the question. I feel like he doesn't care anymore and doesn't respect the boundary I set that I do not want to be in a relationship with someone who watches porn Thank you for reading that all lol, I just really need advice guys
