He won't admit to his porn addiction

My boyfriend who I live with has an actual addiction that is ruining our sex life and relationship. He chooses porn over sex with me constantly, going on for half a year. Leaving me horny for weeks on end. When we do rarely have sex he has trouble staying hard. He lies about watching it, hides it. Watches it even at work. When he's sleeping he rubs his dick every single night, having wet dreams. And watches videos of skanky girls that isn't even porn but he watches them as well as porn everyday. He recently watched tons of videos of "sexy women truck drivers" and this concerns me because he is a truck driver and there are some women truck drivers that work at his job. I told him I would send him nudes or videos if he felt the urge but he never has asked for them. I have tried to confront him about this addiction maybe 6 different times. He denies it, lies about it, then blames me for being too sensitive and says it's not a big deal, and then promises he will stop watching it. One time he even told ME to apologize to him when he was trying to lie and say he had a virus on his phone. He will then ignore me until I come talk to him and try to make up. He's currently ignoring me for two days now and acts completely unbothered. He even slept on the couch last night. My stomach is in knots. It seems like he's happy with his problem and expects me to learn to live with it. But it's making me depressed. At the beginning of our relationship we had the best sex everyday (at that point I didn't care he watched porn) but he changed real fast. I need help what to do now. He will never go to therapy for this as he won't admit to his problem and seems to like his problem. Any advice please?
