What can I do to save my marriage when my husband is an alcoholic?

Patty M&M asked:

My husband is an alcoholic. We have been married for seven years. I have tried for nearly four years to get him to get help for himself and lead a more sober life. This including a year of marriage counseling. I am moving out next week. I still love him but know I can no longer live with an alcoholic. Is there anything I can do to get him to get help for himself and hopefully save our marriage???
