Get out now. You are also enabling him by giving him excuses/benefit of the doubt etc, just as much as his family are. He's sucked you in to his addiction spiral and knows all he has to do is buy time with a promise.

Saving you is killing me - is a good podcast to listen to from the start. This who are talking of autoimmune issues aren't making it up. Partners and close families of alcoholics can end up mentally, emotionally and physically damaged by being with the addict.
Lots of women also have to deal with risky behaviours around sex and unfaithfulness too. Sexting other people, constant unreliability, weird work "incidents" that are hidden from you, constant failures at just "being there"
What I know from years of this with a parent, then with a partner is that staying with an alcoholic will kill you in a thousand little ways.
You, unlike those married to and financially dependent on a man like this who have children with him that he's ignoring or traumatising, can get out of this now.
You can walk away. You can block his number. You can live again.
If you stay with him, it's a living death. He won't get sober... it's very rare they will do that unless they hit their rock bottom, and trust me, the rock bottom will be something so extreme you will probably get PTSD on the way down to the bottom with them.
I'm sorry to put it so harshly but if my daughter was with an alcoholic I would do everything in my power to get her away from him. It's not love, it's abuse, it's not a relationship, it's the slow torture of the part of you that wants safety and security. The anxiety that you have now will be triple fold as the illness progresses.
He will start passing out anywhere and everywhere.
He will piss himself, piss in the bed, get up in the night and start pissing in the corner of your bedroom.
He will start to smell like acidic plastic as his insides rot
He will start to develop brain damage from drinking and you'll wonder if he has alcoholic dementia and how you will cope then, especially once he gets violent.
You'll be alone amongst your peers - because once you tell them of what's really going on and they warn you away and you refuse to listen, you won't be able to speak about it again to them. You'll be alone.
Every bit of pride you have will diminish once you are washing his piss, shit and vomit out of your clothes, off your sofa.
He will sabotage every nice occasion - Christmas, birthdays, work dos, every nice thing you do will be marred by some extreme appalling behaviour that will humiliate you and embarrass you in front of others.
You in a party dress with a panicked look and him humiliating you in public.
He will be unreliable around money - he will be spending hundreds on his booze every month and there won't be the money for bills.
Every thing you are doing to help him right now is probably enabling him. Unless you go to Alanon or some other support for partners, you'll keep doing this until it gets worse. The criticism you have for his family, is also you finding excuses for his behaviour, it's you as much as them. So save your judgement for yourself and do what they can't do.
Leave.
