By remaining with him, you are condoning his drinking. Leaving will make you happier in the long run, and MAY, make him realise what he's done to both of you.
Either way, there would appear to be no future for either of you, if you remain in you present situation.
Alcoholics are difficult to deal with, but as someone said, the first step is for them to recognise they have a problem, and the second is for them to decide to do something about it.
I wish you courage and strength to make the right decision, whatever one you make, I hope things improve in your life.
