I am dealing with the exact same thing right now, it's very difficult to go through. I myself am being treated for depression and alcohol abuse. I am on medication and see a therapist once a week. However, since I began treatment my husband's alcohol abuse has become much worse. He drinks to the point of stumbling, running into things and even drinking so much that he is sick for 2 days. He denies getting sick is alcohol poisoning, and claims he must have caught a bug. He doesn't believe I should be on meds or that my therapy will do me any good, which it definitely has. Since he doesn't believe in my outreach for help, I know he will not get help. He is in complete denial and it truly scares me, particulalrly with him getting so sick and stumbling so often.
My children have been so happy since I haven't been drinking, and now that I'm sober all of the time and not just some of the time, I realize what a profound affect it was having on them. Their father's drinking still affects them and it makes me so sad and angry. We could be doing this together, but instead he makes my healing even harder by his behavior. It's taken me a long time, but I've finally decided I've done everything I can to help him, I need to focus on myself and the kids now. I am working out a plan to leave, and once I have it in place, it unfortunately is ultimatum time. He needs to choose his family or his drinking, but he can't have both anymore. I will try to get better with him, but if I have to do it on my own, away from him I will. Nothing is more important to me than my children's well being and if we have to start over ourselves for them to have a healthy childhood, then I've decided that is what will have to happen.
Good luck to you. I hope your husband doesn't continue to live in denial!
