I have waited over 20 years for my stbxah to get hit with the serenity stick. Doesn't work.
He has no intention on getting better unless his life has become unmanageable and he has hit rock bottom. From my perspective, you are wasting your time. Work on you...
Where you are going to go, save some money on the side, speak to an attorney, go to alanon meetings, and get strong. You will need that when you are really ready to walk. I have wasted 26 years waiting. Learn from us, hoping and praying for him to get sober will never work, as love can not cure alcoholism.
Take care of yourself ONLY!!
