I’m sorry for what you are going through. I have just recently decided to be down with my AW as well and it is not an easy choice to make. But I have faith in this site for the support that they have shown me in the last few weeks here. Just have to stay strong and look at the bigger future and the happiness that come with it. It is only day one with me and I already feel relieved in what I choose because I no longer have to put up with her and her drinking. It will get better and that what you need to strive for. Keep on posting and keep your head up.
Hugs to you as this is not easy but one foot I front of the other.
