New to this, bf third time caught

Hello everyone, about 3 months ago I found out about my boyfriends porn addiction. it happend by me putting a few things together in my mind, him wanting me to have sex with other men whil he watched, however compleatly unintrested in sex, he promised he would stop watching it. one week later he admitted to watching it again, and again said he wiuld stop. then two days ago I went on my laptop to find he had left incognito mode (porn site open) I went mad, he promised it was only the once but then admitted that he hasnt really stopped looking at porn however he no longer masturbates. I really don't know what to do, he just is telling me he will stop but I cant really see how thats possible without professional help?? I doubt he will be so careless next time so I doubt ill be able to find proof that hes been on porn ever again (I do an overnight shift at least once a week) I feel so lost, does anyone have any words of advice?? thank you in advance

 

Hello, thankyou so much for your reply, when this all fist came out I tryed to make him look at that website, he didnt seem that intrested. I think the main issue could be that he doesnt think is as big a deal as it is. I am probly going to have to threaten/ walk away. thank you so much again xx
