BF won’t stop looking at other girls

My (23F) boyfriend (25M) and I have been together 3 years. There has been a few times in the past I caught him looking up other girls on social media, not girls we know but more so girls famous for explicit videos, gym videos things of that sort. This only started to become a thing about a year or 2 ago I think.

Anyway, I said it to him before when I saw his TikTok search history that I was not comfortable with it and that it’s something I would nearly consider cheating since there is a sexual nature behind it all. He said he would stop but apparently “forgot” until one day I see it again. I say it again I’m not comfortable and it became a huge argument. This time around he just tried to act like he never knew it was an issue and tried to just blow it off and pretend it never happened before. We have the argument talk it through and again confirm that this shouldn’t be done and I’m not comfortable with it. He agrees and apologises says he’s wrong.

Finally I feel like I can trust him again. Months go by and nothing happens until one day I see him looking up “American girl onlyfans” on Reddit, except replace American with our nationality. We come from a very small country so there is a huge chance he could have known somebody. AGAIN I tell him this isn’t right and we have another huge argument. This time he takes full responsibility and acts like he’s fully in the wrong whereas before he would get defensive. Again I think everything’s okay.

Now, why I’m writing this. The last couple of months he’s been extremely weird with his phone and last night I finally managed to look through his phone. His search histories are all weirdly clear with full days/weeks missing on google or TikTok. Then his TikTok and Instagram recommended searches/videos just said it all. Same thing again, except I feel like this time it was a lot more than before. There were so many videos of girls bouncing their boobs and butt into the camera, advertising only fans and p**n videos all those things. I don’t know what to do if I should say something again or not. I feel like there’s going to be no change but I also feel extremely disrespected. One side of me thinks I should end it with him as we have other issues as well that add to it but the other side of me of course doesn’t want to break up.

We are currently living in a different country together which would make breaking up really hard. I also have been saying I wanted us to start getting more serious the last few months such as engagement or baby but now I feel like a fool and can’t do any of these things with this person as they continuously disrespect me by looking at these other girls who I’ll never be able to compete with.

In the past he blamed me and our s*x life as the reason for looking at these telling me I don’t pleasure him enough etc. it just makes me feel so shit about myself thinking that I’m the reason for all this.

Do I bother saying it to him ? Do I break up with him ? Do I just post a photo of me in a bikini and give him a taste of his own medicine ?
