save my marriage!?

we've been married for 2 weeks, been in this relationship for 5 years and I just found out that in his heart i am on the 3rd place after his family and his brother(who lives with us and I cannot stand) because of him we have fights all the time and we are both stresses out. I made him choose to live with me or his brother and he choose his brother.
that moment I packed my stuff and left. I came back 2 days later because he is my EVERYTHING. He cannot trust me anymore because I might do the same thing in the future when we'll have other problems facing us. I cannot believe that he doesn't think of this marriage as his new life and his new family…what should I do?

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

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???
