Husband is only interested in BJ's help!!!

My husband is only ever interested in Blowjobs. We have sex once or twice per month and when we do it's a quickie in which I don't orgasm. I've tried everything, when I press the issue he'll 'make-up for it' by promising me that he'll put in more effort to please me and he does so once or twice (he'll last longer, he'll make sure I orgasm etc). Then he's back to his old habbits of completely neglecting me. He's always tired and/or has another reason. Until I start pressing the issue again.

He receives daily blowjobs (more often than not multiple per day). Don't tell me to stop giving because I've tried that and it only made our relationship worse.

I've suspected he has a porn addiction for the past 2 years, and he finally confessed. He watches porn every day. Not just any porn, he's only interested in blowjobs (he skips the sex part of the video if there is one). It's not because he's unhappy with me (he is), he has to masturbate because of anger issues. I never had a problem with porn btw, now I make sure I'm not in the house when he does it (I'll be in the garden, gardening or something) because I don't want to hear him do it (it reminds me of his constant lying).

He doesn't seem interested in sex whatsoever. I honestly don't know what to do.

Giving him blowjobs is the only physical way we can connect. If I take them away I'll end up with something that feels like a roommate. I know he loves me, but what's wrong with him? How do I make him understand I too have needs?
