Boyfriend with porn addiction?

We’ve been together about 3 years and I just found out 2 months ago and I’m struggling to deal with this as it makes me insecure at as he’s cheated (sex /texting/nudes) before. We have 2 babies together I’m 20 he’s 26 and y’all this is killing me. I’ve never felt so belittled in a relationship and I’m confused scared hopeless and angry. He watches intense gang bang or anal fisting or orgy porn every single morning before work and he doesn’t even attempt to make any sexual advances towards me in the morning. When I ask him he just says that I say I don’t want sex so he has to go jack off but we have great ( for both partners) sex 5-7 times a week and I never tell him no in fear he’ll go cheat again or jack off to real women he knows like he’s done before. I’ve told him it disgusts me to my core and it is cheating which he’s also done. I just don’t know what to do I don’t have any money family friends or places to stay I can’t leave and I just want solace and peace on my own. This man is emotionally torturing me and manipulating me and I have nowhere to go. I fxcking hate him guys but my heart won’t give up even if I did have somewhere to go. I’m so alone and broken😢
