Husband's drinking problem

He drinks too much and knows it but doesn't want to get help. He owns his own summer business and doesn't work in the winter and still gets paid so he drinks all night and sleeps off the hang over all day.

Last night he drank 3 liters of wine and a 6 pack of beer and is still sleeping. That's not normal right?

I'm so lonely. I do everything for our toddler all by myself because he doesn't get up until dinner. What do I do?
