AIO I feel like I should leave him. Or I’m I overreacting?

how can I talk to him about his porn addiction?

For reference my finance 27 me 24 have been together for 2 years we recently decided to finalize things for our marriage in October earlier in our relationship I used to catch him watching porn all the time ngl it used to bother me a lot but I tried to get open to it and fuck him while watching porn even go to nude beach in a bathing suite so he can just look around and enjoy cuz it seemed like he wanted to try that really badly I comprismed a lot for him to get whatever he pleases and now he’s refusing sex cuz he’s too tried. I don’t want to assume he’s cheating… but I know he’s watching porn and saw a bunch of only fans content on his phone and it made me so upset I told him I didn’t care he watched it it’s normal to be horny but I’ve been asking to have sex and he’s literally too tired to because he cums all night to porn I’m afraid he has.porn addition and every time I talk about it I get slammed and he accused me of cheating etc not sure what to do … I don’t wanna be hypocrite because I do watch porn time to time too but I voice my opinion so many times about how I don’t wanna see what he’s watching cuz it makes me feel insecure at times because he makes comments about my body. What should I do for reference the first screenshot was yesterday morning and today this morning he texted me this
