Exwifebegins has spoken some very sensible and honest words, listen to her.
I have mixed emotions for you, I know drink can be truly evil, it too cost my brother, his home, children, job, family and then last July it cost him his life.
I went through various stages with my brother, sympathy, anger, frustration and ultimately against everything I thought was right, I had to walk away. He died a very angry lonely man and my heart aches for him. But it was affecting my life, full time work, two small children, very elderly unwell parents on both sides and I couldn't deal with it.
Your husband may feel he has got to walk away, to preserve his self respect, sanity and peace of mind. Maybe he will get through it but you need to never drink again, not ever, no matter what happens with your husband, you've crossed a line, you cannot handle alcohol and it stops now.
I have sympathy with you, but only if you stop drinking now, maybe your husband will feel the same.
I have more sympathy with your husband and his heart must be breaking, does he have a good network to support him? Encourage him to talk to people, he needs to do that and not take it all on himself.
And you need to listen to him, I'm sure it will hurt but listen, apologise and listen again.
Now do not wallow in self pity, get up, do whatever you normally do during the day and ensure your daughter is not upset by any of this.
Good luck
