Aloha Taurus and welcome to the board...It's good you got here.  I suggest that you learn as much about alcoholism, the disease, as you can.  For me and I am one...alcoholics "in sobriety" don't drink at all...once we drink we do not stop on our own.  We need the help of other sober alcoholics.  Alcoholism is a compulsion of the mind with an allergy of the body...we want to drink and our bodies get sick of it when we do...along with our spouses, friends, associates and families.  Did your alcoholic take an assessment or such to define that he is alcoholic?  Alcohol is a mind and mood altering chemical and so not angry to angry, beligerent, rageful is often normal.  Alcohol actually triggers anger and rage from my experiences and education there is a reason for it and there is also a name for the dual personalities..."Dr. Jekyll and Mr. Hyde" from the horror story.  

So what you're getting from being loyal, committed and supportive of your alcoholic is what we got ourselves, nothing but more of the same treatment.  That is also normal for alcoholism.  As long as we put in the effort for them they don't and don't have to...they get more opportunities to drink or use and as they get drunker and more crazy we get more sick and tired and crazy ourselves.  What we do is called enabling because the result of it is that what we do enables the alcoholic or alcoholic/addict to drink and or use more.  We have great intentions and commitment which just results in us wondering what we are doing wrong and why we never get closer to solution. There is a valid reason why that happens and it is in the Al-Anon Family Groups recovery program.  

Go look for the hotline number for Al-Anon in your area from the white pages of your local telephone book.   Call that number and find out where and when were get together in our face to face meetings and then come join us.  When you're there take a gander at all of the literature which is available to and for the family, friends and associates of alcoholics and or alcoholic/addicts (my wife was one) and make it a point to keep going back to the meetings.   You can also come here anytime because MIP is in support of your peace of mind and serenity.    ((((hugs))))
