I've never got him to see my point of view
That's why you have to start asking questions here about how long this relationship can go on.
He has let you down very badly, and is treating you worse than he might treat a mortal enemy.
He is being nasty now because he has competition for your attention. By the sound of it, he is gripped by a powerful case of jealousy. You got attention from the medical staff, you are giving attention to the baby, you were not available to dance attention on him while you almost died. He is punishing you for thinking you could abandon your job like that.
I would not ask him to hold the baby or help you out in any way. I would not leave him alone with the baby, ever. This man sounds dangerous.
You are describing a man completely devoid of empathy. He is behaving like this because he gets a sense of superiority from treating you appallingly. He has not lost his marbles - he hides his terrible behaviour from everyone else.
I know it's hard to get your head together after childbirth sometimes, and it's hard to approach the idea that you may be married to someone who is completely incapable of loving you, an emotional vampire who is capable of abusing you horribly, but if you have any energy and you feel up to it, I recommend you look up malignant narcissism.
Is there anywhere else you could go? Do you have family nearby? Do you have anyone who could come and stay for a while?
Could you check into a local hotel for a while?
You could take a taxi..
I recommend that you call the unit where you were treated and ask to talk to someone there about your situation. The treatment he is giving you is extremely abusive.
