Bf watches porn…a lot

My bf watches porn excessively ( by that I mean an addict), from sun up to sun down everyday. I’ve tried to be okay with it but I’m not. It’s become an issue that I’ve talked about with him. I sometimes don’t feel like I am enough for him. He doesn’t see nothing wrong with it. He tells me that I am enough, that he finds me attractive etc. He then goes to say that I’m insecure 🤷🏻‍♀️

Don’t know what to do. Any thoughts?
