Hi Bobbysocks, you are certainly in the right forum, and in the right place. You will find lots of support from others who have been through the pain of living with alcoholics.
The first thing that i thought of was, have you made up your mind to part with your husband, or is there some wriggle room like he can stay if he stops drinking? If you've decided he has to go whatever, then seeking legal advice and perhaps domestic violence advice. You have access to the internet so you can research where you can go for the practical side of things which involve court orders etc. This may be the only way of getting him out of the house if he refuses to move.
Be careful, make a plan, do your research and have a support network. There is a lot of reading on this site, and many threads and posts which follow people making the same journey as you. Best wishes.
