Accept the fact that you can't force your husband to stop drinking. Your love and care for him, no matter how great, isn't enough to break his addiction. He will only get better if he chooses to, according to HelpGuide.

Compare the benefits -- and costs -- of staying in your marriage. Some things to think about are how this decision will affect other people, and what your life will be like, five years after leaving your husband.

Talk to your husband about your decision when he's sober. Explain to him how his alcoholism is hurting you, and that you need to leave him. Pick out a few examples of the times his alcoholism affected you. Have this conversation with him in a quiet, but public place, such as a park. However, if you have any reason to fear that he might react violently, simply leave him a note. Your own safety must always be your first priority.

Pack all of your belongings, and move out of your house. If you're unable to afford an apartment, stay with a relative, or at a women's shelter, until you're able to get back on your feet. Don't tell your husband where you'll be staying, to prevent him from following you. This is especially important if you've been a victim of domestic violence.

Cut off all contact with your husband. Be sure to quickly change your cell phone number and email address. It will be more difficult to move on with your life, if you continue to talk to him.
