Is staying in a relationship with someone who has a porn addiction worth it?

I love my boyfriend, we’ve been together for a year and a half. About two months ago I found out my boyfriend was jacking off everyday multiple times a day to multiple upon multiple different videos and photos of girls and one OnlyFans purchase (monthly payment). Once I found out I broke up with him for a week, and then I caved and got back into a relationship with him. I told him if I find anything porn related, or any pictures of girls and I’m leaving.

He lied to me when i found out about his addiction and when I caught him he wanted me to give him his phone back. I knew he watch porn but DAMNNNN why so much? We cried and cried and a big part of me resents him for it still. I don’t feel like to the prettiest to him anymore and I don’t know if I will ever. That being said, he gives me full access to his phone now. And he’s seeking therapy, it took him a while but he has his first meeting in a couple of days and I told him he needed to go if he wants our relationship to work (the therapist is not an addiction therapist but I’m making it clear to him that’s the first thing I want him to mention)

People in my shoes, how did you catch your partner was back at their addiction again? It’s easy to go incognito.

We’ve had no problems besides his addiction. Sometimes, every now and then (like rn), the thought of it just makes me angry. He says he’s not looking at porn and he hasn’t since the day I found out. He gives me full access to his phone (he lets me look at messages, any app I want, his search history, everything), He doesn’t take his phone into the restroom anymore, he started going to the gym and picking up healthier eating habits, and he’s about to see a therapist in two days.

I’d like to know your thoughts, does this relationship have a chance?
