I'm sorry you are hurting so much.
I would be too after treatment like that.
I suggest you stop giving him money and set some boundaries for his treatment of you.
Verbal abuse such as you are describing should never be tolerated from anyone.
It may mean you need to go no contact with him for awhile.
I understand that early recovery is a tough time emotionally as I am also a recovered alcoholic, however, it seems you are being used as a scapegoat and emotional dumping ground.
This isn't good for you or him.
You are quite right that no amount of money will be enough so stop the supply.
Glad you are here and I'm sending you some big hugs--
You sounds like a wonderful, loving, sensitive mother to me.
