Porn is ruining my sex life

I feel like my husband has a weird addiction to porn. I tried getting him help but I feel like his last doctor was just like heres some antidepressants no go home you're fixed instead of really addressing why when and how did the issue start. Now before everything thinks I'm overreacting i catch him watching porn and masturbating multiple times a day sometimes. If hes masturbating hes watching porn. I know he watches it every morning. I've literally woke up and he's doing it right next to me. Honestly at this point I've just been letting it go even sometimes. Which makes me start feeling bad about myself because its like whats wrong with me why would he rather watch porn than have sex with his wife thats more than willing and laying next to him. Am I that unattractive to him. We've only been together a little under 3 yrs. Its also not like I'm not willing and haven't offered to try new things sexually as well as tried some. Honestly I'm lucky if we have sex 3-4 times a cycle and most the time i feel like its my idea which makes me feel pathetic or like I'm begging for sex. The porn addiction is really starting to hurt my feelings. I've never even been someone thats anti porn I think its healthy to explore and be comfortable with you're own body. I'm just not okay with feeling like he'd rather masturbate to porn than have sex with me. And I'm not okay with him watching it everyday multiple times a day sometimes. Its ruining my self esteem, my sex life, probably the chance of us ever getting pregnant and honestly without changes our marriage will probably be next. Don't get me wrong hes a great guy besides this one thing but situation is so out of control its starting to make me depressed, ugly, and feel pathetic. Has anyone else went through is issue or is going through this issue. Any suggestions other than you should just leave your husband on how to communicate what I'm feeling and how to get him help. Because I'm not getting through to him obviously. I feel helpless and trapped in repeating cycle where he'll do great for awhile and not do it but usually only after i get to a boiling point and go off

then he goes right back to it.
