Porn addiction help

I've been with my boyfriend a year and a half. Since the very beginning I knew he'd watch porn after I fell asleep on nights we didn't have sex. It didn't bother me then. Sometimes I'd see him touch himself sometimes not. But like everything in the beginning of a relationship, nothing bothers you. Then one day I just became bothered. I felt like I wasn't good enough. He'd watch porn while I was "sleeping" next to him, he'd click on links with sexy girls on fb, and his search history on insta had things like "#sexylingerie". I finally confronted him casually that it bothered me and he said he'd stop. Well I caught him again one night right next to me. I cried hysterically that he was ruining my self esteem and that I didn't feel like I was beautiful. It crushed me. He admitted it was a habit from his last relationship because they never had sex. Well would u look at that..I JUST caught him again while I was "sleeping" he got very defensive telling me he uses it to learn new things. He brought up the habit and got mad when I called it an addiction. He says it's a "habit". Same shit to me. He says he doesn't NEED to watch it but that he just does it out of habit and boredom. Am I crazy for feeling hurt? I feel like my feelings were disrespected. I feel so ugly and so disgusting compared to these girls he sees. And on a side no I don't even care that he watches porn I just don't want it done with me IN THE SAME ROOM. Someone help :(
