All of these things are manageable, even taken all at once, with patience and care. It's his addiction that is making all of them unmanageable. It's choosing to deal with stress not by working towards solutions to these problems, but by escaping into the oblivion of booze. That's a choice he is making, while deflecting his guilt onto you and causing deterioration in your relationship.
The "fronts" I was referring to are these circular, blaming conversations he has with you that make you question whether you are over-reacting. We can't have perspective when we are knee-deep in the problem. Finding a way to detach from these conversations, to avoid getting embroiled in them as if he were being logical is crucial to your state of mind right now.
