Wow, Chero, I am sorry this happened. It sounds like classic alcoholic manipulation to me. He sounds angry that you won't be taking care of him any more, he now has to take care of himself. Threatening to leave is so classic. "you hurt me so I am going to leave." ugh. Classic victim, putting all of the blame for what he is doing back on you.
I see this so clearly, I remember thinking like your huband. The fact is it is pointless to reason with him or take anything he says too seriously. He's a drunk and he'll do, say, try anything to keep his situation going and keep his disease active. Been there, done that.

Hang in there, honey. You are a little stronger everyday and you are starsting to recognize this.
Love,
