(((Karen))) I am so sorry that you are going through this. It truly can be a nightmare. Have you checked out any Al-anon meetings in your area. They can help you learn how to deal with an active alcoholic.
Unfortunately, unless Brandon wants help, there isn't much you can do for him. If you will read the stickies at the top of this forum, you will see the experiences of many others who have been exactly where you are. Our focus here is mainly on you and your well-being.
Welcome to SR. There is much wisdom and experience here. Please come back and spend some time with us. Even if you just post to vent, that can be helpful, too. Please take care of yourself.
