Welcome to our community!! I am so glad that you are reaching out and asking for help. I agree with both Lookingout and Bluidkiti.......Please start with Alanon. You will find support from people who can identify with you and who can give you the tools to take of yourself. You must understand that even though you are a couple you are individuals. He must walk HIS OWN path to recovery and to be successful, he must do it for himself. I suggest you do whatever is necessary to take care of yourself. There is an excellent book titled "Boundaries: When to Say Yes and When to Say No" authored by John Townsend and Henry Cloud that many people have found helpful.
Please visit the links provided by Bluidkiti, there is lots of imformation there, too. Continue to come here and post. Just know that you are not alone.
